Re: Runaway memory usage in Access Connections AcSvc.exe

2008-09-04, 15:31 PM

I've been monitoring it's memory usage closely since I installed it on my machine (XP) yesterday. It used around 208M total memory, yesterday, after a few hours and a couple location switches. This morning, I see it is up to 310M for no reason I can imagine. The number I'm reporting includes virtual memory, and has actually grown slightly since I started writing this.

 

My experiences with earlier versions taking up over a Gig took several days to develop, so I can't say this looks very promising to me. But maybe bsnf can comment as to whether the memory usage I'm reporting sounds normal and expected. If there's any other information I can provide, let me know.

I still am running on version 4.42 (vista sp1) on a thinkpad t61 and memory usage is 15mb

 

personally I think even 200mb for something so basic is outrageous, pls let us know how this develops

 

on my thinkpad t42p with xp sp2 it is only using about 30mb (this machine has been up and running 8 days)

Re: Runaway memory usage in Access Connections AcSvc.exe

Up to 321 Meg now (including 45 min in sleep mode, while I changed locations), with a peak of 338M recorded (by TaskInfo). Yes, it does seem like a lot of memory, even before it starts leaking. This is in addition to another 43Meg or so the Access Connections Profile Manager Service, 44 Meg for the SvcGuiHelper app, 46M for the Tray application, 91M for the tray status application (my numbers at the moment, and I think I've seen at least one of these also leak memory over time, but I'm ignoring that for now while focusing on the biggest offender, the main service).

 

I'm assuming the base memory usage might have to with frameworks used which are out of control of the Access Connections developers (short of re-architecting the app), so I haven't been complaining about that (and since the leak is a much bigger concern). But as a developer myself, I'd be curious to hear what this memory usage stems from.

ericjs,

 

When I replied to the thread I was not aware of a issue on XP.

The issue was earlier mentioned on Vista SP1 and that issue is fixed in AC 5.02.

 

I will investigate the issue on XP and get back to you, may need your help if I need additional information.

 

Did you have this issue on AC 4.52

or did this issue start with AC 5.0.

 

 

What service pack is installed on the system.

I didn't realize the problem might be OS-specific. I definitely experienced the problem pre-5.0, though I'm not sure I'll be able to determine which version exactly I was running prior to my having installed the 5.0 version and then the 5.02 version (though I will see if I can find out). Does the ThinkVantage system update keep some kind of log I could check?

 

But I think I've seen the problem for years, including on my previous thinkpad (also XP), which was running a version still named "IBM Access Connections". I'm running XP SP3.

I tried Access Connection 5.02 posted earlier on this forum on Vista. It is definitely a big improvement, and new GUI looks very good. Memory usage of AC main service (AcSvc) is still very excessive though - the service hogged 205 mb on my system right away, and it stayed at that level throughout several location switches and sleep/wake-up cycles.

 

200 megabytes for a service which only purpose is to support switching network profiles, is still way too much - it's not right. I hope Lenovo offers final working solution soon.

I tried the AC 5.02 too and I must say that it is better than it was - but nothing extra. AcSvc service has about 86 MB of memory after some location switching and others. But this value is not changing more than about 5 MB (from start) - it is ok but less memory use will be better. But yes, better than 1GB and more :smileywink: thanks

Re: Runaway memory usage in Access Connections AcSvc.exe

Up to 440Meg now. Other ACSvc process stats which seem to have increased since yesterday evening are the number of threads (28 now vs 26 before), and the number of handles (612 vs 596 before). But I've only just started noting these, so I'm not sure how consistent that pattern is.

 

The memory usage of Tray Status Application, ACWLIcon.exe has also gone up significantly over the past day or so, up to 135M, up from the 91M last time I checked itabout a day ago.The other 3 AC processes have remained in mid 40s.

I concur with previous report. Access Connections 5.02 is still leaking memory on Vista, although not as fast. It's been second day now and it's up to 420 megabytes here - no sings of slowing down. I didn't observe any pattern of what triggerred this - at one occasion it was definitely when I brought up "Network and Sharing Center".

This is definite sign of bad or non-existent QA in their engineering team.

5.02 is working a lot better for me. I have switched networks a few times. AcSvc is sitting at 8MB. I am using Vista x64 SP1 w/4GB R61. My Intel drivers are 11.5.1.15.
