KAV updates task causing system freeze for a while, KAV updates task causing system freeze for a while Options

[kelvinng]

Recently, quite a number of clients installed with KAV workstation 5.0.712 & 6.0.3.837 is complaining their system freeze for a while when ever KAV update task is running. it happened to me notebook too.

note : update task was global update task created via Admin Kit & push to few hundred clients with schedule update run every one hour with interval 15 minutes

We have the same problem in our company....freezing computers during update. We use KAV WKS 6.0.3.837....again trouble with Kaspersky....

Ditto here. PC hangs during update so bad that I had to change the updates to only happen every couple of hours.

I am also having frequent crashes and dumps...

This is not fun at all!!!

By the way we too are on 6.0.3.837

Hi,

we are having same issue here as well and we are running KAV workstation 6.0.3.837 - the computer freezes for a short time during update task.

[kelvinng]

from Admin Kit Help;
A randomized schedule automatically spreads tasks assigned to clients over a specified time interval. This feature helps Administration Server process numerous concurrent client requests as tasks are started on multiple client computers.
Select the Randomize the task start with interval (min.) checkbox and specify the randomization interval in minutes to enable clients to contact the Administration Server throughout this interval, starting from the task start time.
By default, this checkbox is unchecked

some questions;
1) shall i change the schedule update to every 2 hours instead of 1 hour?
2) shall i increase the interval time to 10 or 15 minutes?
3) shall i checked on 'Stop if the task is taking longer than (min)' & set it to 30 or 60 minutes?
will changing of above settings help solving the problem?
we have around 400 clients installed with KAV 6.0.837 & some with 5.0.712. admin kit version is 6.0.1591.
attached the snapshot of global update task setting for workstations on admin kit.

Kelvin, try to stop the scheduler first. Check existing update list in KAK, manually run the update in KAK and check the date.
If your KAK able to update with newer pattern etc, your proxy and updater is OK.
If not, try to update directly from you pc via internet to check your environment for accessing *.geo.kaspersky.com

This is what I did in my environment. Hope useful to you as well. My 2 Yen

For everyone who have problem with system hang during update:
Please tell me which version of Network Agent is installed?

I think, I decreased a bit this freeze, but I need this information to confirm a bug.

We recently upgraded our Kaspersky Server to version 6.0.1710, so most or our client computers are still running previous network agent version 6.0.1591 and not 6.0.1710. Do you think this could be the problem?

[Jacek]

In my environment: with Network Agent 6.0.1710 computer freezes for about 2-5 minutes (!) during update.
With NA 6.0.1591 (the same workstation) it freezes but from 10-60 seconds.

All of my agents are at 6.0.1710 and my workstations freeze anywhere from 60 seconds to 180 seconds...

Could you downgrade network agent to 6.0.1591 and check again?

[smithbro]

Could you downgrade network agent to 6.0.1591 and check again?

I will give it a try and let you know.

i have changed the global update task interval to 30 minutes but users still complaining computer freez problem

[Jacek]

I know there still will be a freeze, but it should be shorter.

We are having a similar problem but many of our workstations slow down to a crawl for up to 20 minutes while the update task is running. During this time the workstation is almost unusable.

Many of our workstations still have 512Mb RAM (but I don't think we should have to upgrade the RAM just to run a AV application).

All of our agents are v6.0.1710 (we only installed KAV at the end of last year so have never run an earlier version).

Would downgrading to v6.0.1591 help? if so, how do we do this?

The system freezing, is this happening on single or multi-core CPUs?

I am noticing while I work on these slowdown problems that since I have a 2-core Intel, the update task essentially maxes out one core, but the other core is relatively slow so I don't see the performance hit. I still see the memory usage of AVP.exe climb to 130+MB though. I am also using the 1710 version of Network Agent. But I may try the old version if I need to.

it happened again yesterday noon , the global update task run & freeze system for a while.
i'm using 6.0.1591 network age

[JustinLFS]

I installed the NetAgent 6.0.1591 (msi) from the FTP after removing the one I had for GPO (6.0.1710). Used KLMover to point it to the proper admin server. The initial update I did used significantly less memory, about 30MB (way down from 150MB) so I was hopeful this would alleviate some of the freezing. However shortly after I tried it again and the memory usage spiked back up to the 150MB range. It doesn't appear the Agent has much to do with it from what I can tell. I have a good CPU though so I don't notice the slowdown really if at all.

Doing the update task and seeing the output, it appears to be parsing an XML file (I am guessing it is the signature list) - av-i386-0607g.xml, memory usage is about 15-20MB during the download, and when File updated events appear, memory usage hits the 100+MB mark, even though the actual files are tiny. CPU usage is high during the download, memory use is high during the writes.

I am using Vista SP1 Business. I also tried unticking the option for using Passive FTP in the update settings but it didn't make a difference either. No proxy is used. I am fully patched and am using the latest NIC and HD controller drivers.

I can confirm that this issue exists at a site that is running 6.0.1591.

[kelvinng]

any solution ?
