VSE 8.7i Killing Citrix Servers When Updating

Hi Guys,

We have been running VSE 8.7i on all servers and workstations for months without any problems, but we pushed it out to our 4 TS / Citrix servers yesterday and it completely killed all of them whilst it was doing its initial push and update. By "killed" I mean mcshield.exe using up 100% of the CPU for just over 20 minutes.Once the install had finished and the latest DATs had been downloaded from our EPO server then they all settled down. However, when those 4 Citrix servers have automatically updated to the latest DATs today, we found that the same thing happened... each server is maxed out for 20 minutes.

So are there any specific exclusions we should add for Terminal Services and/or Citrix (I searched but couldnt find any other than just C:\Program Files\Citrix but adding this has not helped) ? If not, can anyone offer any suggestions as to why this is happening and how we can resolve it?

Do you have Patch 4 installed? That fixes several issues with updating and high CPU load.

You can check your patch version with rightclick on the Mcafee icon and About Virus Scan.

Ahh thanks, I should have checked to see if there was a new patch out first! We are currently on patch 3, so I'm installing 4 now on the Citrix servers and will see how it goes. Thanks!

Re: VSE 8.7i Killing Citrix Servers When Updating

Well its not looking very promising so far. Installed patched 4 on 2 of the Citrix servers and straight away after the install finished they both sat with Mcshield.exe using 99% of the CPU for about 15 minutes

Check out this thread here:

It's also about Citrix issues.

Re: VSE 8.7i Killing Citrix Servers When Updating

Thanks, I've had a look but unfortunately there are not really any definitive answers in that thread (so I've posted in it asking if someone can share their solution).

From that thread though it seems like VSE 8.5 seems to work OK on the Citrix servers so I guess we could install that instead of 8.7, as 8.5 must be better than nothing and better than having our servers freeze every day...
