Also ensure you are using the latest support pack (drivers). There were
known issues with the raid drivers about 2 years ago. If your build hasn't
been updated, this maybe a path to try.

Cheers,
Jeremy.

had the same problem on our dl360's. did you buy them with bbwc module?
found
out that the raid controller comes without write cache. check physical
disk
%disk time during normal operation and user logon / logoff. the missing
cache can cause the server to stop responding for a few secs. see
CTX103277
for details.

Subject: [THIN] Typing Delay - Need some expert advice......please!!!!

Hi everyone,

We're experiencing intermittent (but frequent) typing delays on both of
our
Citrix environments (one production one soon-to-be-production) but I
feel
I've been down almost all of the normal paths.  Here are the stats:

Production environment: 5 servers, DL360 G2s, MF XP 1.0, Microsoft
Windows
2000 Advanced SP3 + KB324446, KB824146, KB81669 Hotfixes, 2GB RAM,
Office
2000 Test environment: 6 servers, DL380 G4s, MF XP 3.0, Microsoft
Windows
2000 Advanced SP4 + All hotfixes (as of last week) + all Citrix
hotfixes,
Office 2003

In both environments, we get occasional typing delays from users for a
few
seconds when they're using email (Outlook is editor, not Word).
CPU/Memory are both fine during the reported sluggishness.  Network
latency
is well below the threshold as this is happening even on the local LAN
segement.  I've run bandwith and ping testing and this comes back with
890
MB/sec and less than 1 ms delay time.  Port speed and duplex has also
been
locked down on the server NICs and switchports....
But we're still having a noticible issue.

With the non-production boxes, only a handful of users are on them, so
maybe
1 person per server and there's still a problem... I'm at my wit's end
and
I've already opened a ticket with Citrix, but it's a painful process
since
it's only an intermittent issue.  Speedscreen is not turned on.  As I
mentioned, since users on the same subnet with a Gigabit connection are
also
having the problem, I don't see how it can be bandwith/latency related.
I'd
rather not mask the problem before actually finding out the root of it.
I've tried disabling all of the Citrix virtual channels and still no
luck..

Has anyone else had this happen?  Any ideas on what I might be missing?
Does this sound Citrix related or network related?  Any gut feelings?
Any help would be greatly appreciated.
