I have experienced problems like this before. Running a farm of 35 NT
servers (terminal server no citrix), and about 40 users per box during
peak times. We would get 1450 errors and would have to remove servers
from the farm. I got to a stage where half the farm was rebooted each
night to keep it running!!
We found once we removed trend AV, the servers would stay up for weeks
and handle more users.
We may have hit a resource limit once AV was installed and could have
been teetering on the edge, however, I still believe it was a trend
thread leak issue but have been unable to get it resolved so far.
I should mention the servers weren't small either, 4Gig RAM quad
processor etc. This doesn't mean anything though when NT has hard set
limits for paged pool and non paged pool memory.
Cheers
Doug

Over the years we have seen McAffee cause all kinds of stability and
performance issues. It depends on the version you are using, we are
doing a
large project now with McAfee 7.1 and it seems okay so far....

Subject: [THIN] Yet Another Anti Virus On Citrix Question (hopefully

twist)
This is a little long...
I know the topic of AV and Citrix has been beaten to death here, but I
had
an interesting thing happen the other week and wanted to see if anyone
else
had seen anything similar.
Although we are moving to a shiny new Win2k3/MFXP environment, we
unfortunately have to keep the NT4/MF1.8 servers up for another 6 months
or
so. We have barely been able to get more than 65 users on a server
concurrently. Heavy thin client users with published full desktops.
For years we have worked with Microsoft and Citrix troubleshooting BSOD
issues that have really gone nowhere. As a last ditch attempt, I had
one of
our guys completely remove McAfee off of one of the servers in an
attempt to
eliminate yet another variable.
Not only has that one server stayed up for the past 3 weeks but, due to
bringing it back in to the load incorrectly, it also had 94 users on it.
Before we would get 1450 errors and would constantly run out of registry
quota. All of a sudden that one server was handling 1.5 times its
normal
load.
So that got me to thinking - in our new environment I am seeing closer
to
100 users per server, but the memory usage is obscene. Performance is
acceptable though.
Has anyone else ran in to AV software severely limiting the number of
users
you can support on a server? Is it purely a McAfee thing? One of our
new
hires mentioned that they used McAfee where he came from, replaced it
with
Trend, and nearly doubled the amount of users on a server.
I realize my mileage may very, but if I am truly not crazy and McAfee
could
be the root of all of our issues, I am more than happy to look for
alternative solutions.
One last question, do most of you even run AV software on your Citrix
servers?
Thanks!
