Endpoint Protection SBS 12.0 - Memory issues

This issue has been solved. See solution.

We are using Endpoint Protection Small Business Server 12.0 for some months now.

Although it works quite well we are a bit dissapointed about the amount of memory needed to perform the necessary tasks.

This morning we were once again experiencing heavy activity on the server. As a result I had a look at the different processes and their CPU/Memory usage. First I looked at the five most heavy processes;

  • dbsrv9.exe (566.412 kb -> at one time peaking over 600mb)
  • store.exe (562.724 kb)
  • w3wp.exe (280.624 kb)
  • w3wp.exe (183.168 kb)
  • iexplore.exe (169.496 kb)

Out of these only one is related to Symantec, but sadly this one is the biggest consumer of memory.

I then searched for other Symantec related processes and found:

  • luall.exe (108.512 kb)
  • lucommserver.exe (116.936 kb)
  • lucallbackproxy.exe (at one point more than 400mb — at the moment 7 instances each use between 1mb and 5mb)

So, at times, Endpoint Protection uses up to 1,2 Gb. This is about 20% to 25% of the physical memory present. For a product which is marketed as "the most effective antivirus, anti-malware technologies available in a single, integrated solution" and which "will not slow you down or swallow up system resources." (, accessed on October 28th 2011)

I already found some older posts — most of them locked — which point to similar issues, but I can't seem to find a solution in there.

kind regards,

I already had a look into this some weeks ago but was reluctant to install it. I couldn't seem to find a 'new features / fixed bugs' list so I wasn't really able to evaluate if it would be wise to install it right away.

Just talked this through with a colleague of mine and the upgrade is planned for tomorrow afternoon. If needed I will get back to you.
