csrss.exe using 80% cpu

Hi there,
We've just put our citrix farm running on windows server 2008 (32bit) SP1 into use (30 servers).
The problem weve been having is every 1-2 days we get the odd server where csrss.exe will just go nuts and use all the cpu it can get.
Since these are citrix servers it really slows the system down for the users, but were in a sticky situation since a reboot DC's them so we need to wait till the end of the day before restarting.
Has anyone come across this problem before?
