My Aquasuite 2012-6 is set to run when Windows starts up, and to minimize to the tray. The AS service is on, and starts up with the suite. Open Hardware Monitor also runs at start up. Last night I left the computer on all night. When I went to use it this morning, it could not even get the desktop back. Both the Task Manager and the Resource Monitor showed that the process Aquasuite had used over .87GB, or 870,000KB of private memory. Private memory is the actual hardware memory used by a process that can not be shared with other applications or processes. Together with the sharable memory AS 2012-6 had over 1.25GB of memory it was using. That is clearly way too much.

To restart the computer I had to hit the restart button on the case to restart the machine, because it would not even give me the start menu so I could shut it down that way. On start up AS 2012-6 had about 71,000KB of private memory used, 152,000KB to 155,000KB of total working memory (physical private + sharable physical memory). After the restart the amount of both private and sharable memory that AS 2102-6 uses would fluctuate up and down, with both the low and high points slowly advancing upwards. In the time that it took to type the above sentence, the private memory increased to 81,500KB, with total physical memory at 155,260KB. And it keeps slowly increasing. All logging is disabled.

While a total physical memory use of 155,000K is perfectly acceptable, over 1,250,000KB or 1.25GB is ludicrous. The only thing that I can think of is that, somehow, AS 2012-6 has some sort of memory leak. Open Hardware Monitor does not expand its use of memory, nor did the one other program I left running all night.

Do you guys know of this problem? If you need any more information, please either post or PM me and I'll get whatever I can and send it to you.

PS: After previewing this post and getting ready to push the "Submit" button, the private memory use has increased to over 83,000KB, and the total physical memory to almost 157,000KB.

It is now 4:37 pm, or 16:37. I left AS 2012-6 running after the earlier post, also Resource Monitor and Task Manager. AS 2012-6 is now, just under 4 hours after the first post, above, using: Private (unsharable hardware memory) 371,136KB, Shared (sharable hardware memory) 91, 508 KB. The total is about 467,800KB, this, like the other numbers fluctuates around, up and down, but always trends upward.

Windows 7 - 64 bit

No database engines or backends running.

I do know how to read, and Task Manager and Resource Monitor both showed ONLY aquasuite.exe hogging the memory.

The Task Manager list of services running is pretty big. I'll try to get to it tomorrow morning. If you are looking for a specific service that is related to Aquasuite 2012-6, it is easier to give me the names of the services that Aquasuite is responsible for and let me see whether or not they are running. FWIW Task Manager shows that the process aquasuite.exe does not have any services running.

Edit: Tonight I will leave AS 2012-6 running with ONLY OHM 0.5.1 running to provide it with data. There will be no other programs running. And as of now, the process aquasuite.exe has 378,876KB of memory tied up. Going to bed now.

And now, after the computer has been running and ignored while I fed and walked my Dog, Aquasuite's (2012-6) numbers are as shown below:

Private Memory: above 418,000KB, and climbing

Sharable memory: 81,040 KB seems stable, but will climb much slower than private memory

The New One (Ta-Da!), CPU use by Aquasuite: 35% to 45%, bouncing around between those two percentages quickly, occasionally going as high as upper 40% range, and as low as 29%, either for just a blink of an eye.

This is all ridiculous because when first started AS 2012-6 uses around 100,000KB to 125,000KB of private memory and 5% or less of the processor. And it runs just fine with the resources it starts up with.

I'm going to uninstall 2012-6 and reinstall 2012-5 and see if there is a difference.

PS, after a quick preview and correcting a few typos, AS 2012-6 is up to 458,000 KB, still in same % of CPU utilization range.

Hi, jpmboy:

It looks like you are right about the memory flush then refill cycle AS is supposed to do. Mine has done a few today. But it has also missed one today, and clearly missed a few last night. Maybe Sebastian or Shoggy will have a look at the threads about AS 2012-6. They have probably been off for the holidays, and are now trying to catch up with things.

I'm also quite concerned about the high CPU utilization. Right now Aquasuite 2012-6 alone is bouncing up and down between 40% and lower 50% range. There is no reason for that much CPU usage. Everything else, combined, is utilizing between 2% and 7% (fluctuates rapidly).

The main reason that I bought the AE 5 LT for was to control my water cooling system to keep it quiet and ramp up the fans when temperatures increase due to high CPU loading. It's pretty useless if its software is loading the CPU enough to keep the temperatures up.

AS 2012-6 is also pretty useless if it will hog memory so badly that the computer will occasionally get nearly locked up because one process is reserving 1.25GB or more for use.

Edit: I remembered that older thread you mentioned, but could not find it.

Zitat von »LarryWill729«

Sabastian pointed out the first time a similar issue was brought up that AS2012 used Microsoft.net for everything it does.

Also, when drawing/refreshing graphics, it uses a lot of .net routines that are CPU/resource hogs.

Third, one of the big restrictions they are faced with, specifically making the correct formula for calculating Differntial Temperatures in Farenheight correctly, is that AS2012 is only the GUI interface between the computer operator and the AQ 5 hardware. Once the device is installed and set up through AS2012, the AQ 5 does all the work without the Computer CPU involvement, unless AS2012 is left open on a desktop, then AS2012 uses .net and the AQ 5 hardware to make the pretty pictures.

Result: If I am in power user mode, I sutdown AS2012 and no problems exist. If I am web crawling, AS 2012 is up and doing its thing.

I have not tried to write a program in 30+ years, so I might be over simplifying, but I think I am basically correct.

If not, sorry but I tried.

Larry, whether you are on the right track or not, if Aquacomputer is building graphics displays into AS 2012-6 (or any other version), then they need to know about this so they can fix it. Aquacomputer is (rightly) proud of the graphics capabilities of AS, and they are a bunch of meticulous guys (and, maybe, girls). They would never just leave AS as it is, and say "too bad, it is .net that is causing the problem."

I have confidence that they will fix it somehow. It may take a while because they might have to contact tech support at Microsoft, and they might wait a long time for a reply. But, note that the earlier, beta, versions of AS did not exhibit this problem, at least not to this degree.

While .net is, or can be, a resource hog, I tend to favor jpmboy's theory. The hypothesis of failure of "flush and refill" of memory nearly perfectly fits the symptoms. The only thing that jpmboy's theory does not explain is the slowly increasing use of the processor. That might be tied to the flush and refill failing somehow. But I think AS would not run nicely when first started, which it does, drawing graphics on the desktop, etc., if it was a problem with .net. When first started, AS runs well with only about 73,000KB of memory, and an average of 1.5 to 2 % of processor capability. And it can run with those resources for quite a while before it begins to hog memory. Note that it seems to hog memory first, then start hogging CPU time later on.

I leave all of my temps to display in deg. C, so problems caused by any conversion to deg. F is not an issue with my system. It looks like jpmboy does the same thing, even leaving his flow rates in metric units.

To make my intentions clear I would only like Sebastian or Shoggy to let us know that they are aware of our posts and of the problem. If they know about it, I am quite confident that they will fix it. My main concern with this problem, which is the latest one, is that it may be beginning to hurt AC's image. And that, in turn, might affect their sales/existence. They are a good company with ambitious goals. They work hard to build the AE 5 system and its software, and it would be unfair if they lost out because of some minor bugs, and the intolerance of some users (not us). I'd actually like them to gain market share and get more well known, in a good way, here in the US.
