Memory Leak ?

The process "SpIDerAgent.exe" : after 12 hours, it take about 14Mo. After more than 24 hours, the size exceeds 25MB.
This is not very important, but do you have noticed this?
Dr.Web v5 - spideragent.exe (5.0.1.02160)
Thanks.

After about 4 hours of using the computer, dwengine.exe has used 00:00:06 in CPU time and SpiderAgent.exe 00:00:09. Ofcourse this is not much but it is weird that some agent process uses more cpu than the engine?

It's possible. SpiderAgent tracks status of the antivirus components and displays notifications on the status bar. So it'll take some CPU time (a very small part of it) to query all components and display notifications if something has happened.SpiderAgent.exe also uses more CPU than dwengine.exe according to task manager. spiderui.exe and spidernt.exe don't use CPU at all.
There is nothing weird in this data. Dwengine.exe is currently used only by SpiderGate and SpiderMail components, so if you don't surf Internet a lot, or don't receive a lot of mail that counter will stay low, so there is nothing to worry about. http://forum.drweb.com/public/style_emoticons/default/smile.pngAfter about 4 hours of using the computer, dwengine.exe has used 00:00:06 in CPU time and SpiderAgent.exe 00:00:09.

SpiderGuard works in the other way, so the only way to notice it's activity with task manager is to look at the "System" process.
Btw, dwengine is fast and sleek by it's nature so it won't take a lot of CPU time.

Yep, I'm curious too. If it's not used by SpiderMail then why it is installed with Dr.Web Ativirus for Windows? http://forum.drweb.com/public/style_emoticons/default/tongue.pngThen why do I have it if I have only AV installed without the SpiderMail?

What does this mean? Do I have some unneeded component running because I have the AV only?

Erm, drweb uses dwengine for some innermost activity http://forum.drweb.com/public/style_emoticons/default/smile.png. It almost doesnt use CPU, as you noticed by yourself . Drweb modules will use all the power of dwengine in the nearest future.Then why do I have it running and using CPU if I have only AV installed without the SpiderMail?
No, it doesnt.Does this mean that I have HTTP-scanning enabled but hidden from me because I don't use Security Space?

As I wrote earlier SpiderGuard (real-time or on-the-fly scanner) doesn't use dwengine nor does Dr.Web Scanner. So this test isn't adequate in this case.I disabled the self-protection and killed dwengine.exe from task manager. Downloaded the eicar test file and it was detected and deleted as usual. Scanner also works normally without this dwengine.exe

You can try this steps - disable self-protection then set dwengine service startup type to manual and restart your computer. After reboot you can notice that SpiderMail has failed to stat.
So I guess SpiderMail is using dwengine if it fails to start when dwengine is disabled....
P.S. Don't forget to set dwengine startup type back to automatic after that... http://forum.drweb.com/public/style_emoticons/default/smile.png

It's simply wrong. Try it yourself before write here. SpiderMail will start OK. Check spiderml.log .You can try this steps - disable self-protection then set dwengine service startup type to manual and restart your computer. After reboot you can notice that SpiderMail has failed to stat.

I've tried it on a virtual machine before I've post that message. I've followed the steps as I described them. However due to some lags at OS loading on a virtual machine, or to some other things that don't worth investigation, SpiderMail have started long after the system startup and miniagent showed that SpiderMail failed to start for quite long. I didn't check the logs, of course, http://forum.drweb.com/public/style_emoticons/default/smile.png but still was confused with the result.
After reading your post I've double checked this, and I can confirm that SpiderMail starts disregarding the state of dwengine service.
Damned laggy VM!
Will try to wait more next time for things to settle.
Sorry again.

Boris, it's strange but agent seems to work without dwengine. The only thing that is unavailable is the last update time and a number of virus records. And license manager is not working - you're right.Dr.Web's Agent will not work without Scan Engine. And License Manager will not too.

Back to the original point, SpiderAgent memory usage seems to increase over time. It starts at around 3-4mb for me and is over 10mb after ~7-8 hours.
let's know how much it'll be after 2 or 3 days

Hi Eugeny,let's know how much it'll be after 2 or 3 days
Since 3/16/2009 10:20 AM (GMT +1) SpIDerAgent.exe -> 31 016K
(On Windows XP SP3.)
and continues to grow, slowly.
I will post the new result tomorrow (computer running without interruption)
