20.4 Disabling Random Refresh Might Cause the ZENworks Agent to Crash on a Citrix Server

If Random Refresh for the ZENWorks Agent is disabled and if multiple users log in to the Citrix server at the same time, then all the sessions try to refresh at the same time. This can cause resource contention, and subsequently cause the agent to crash because the cache access is not synchronized. To avoid this, Random Refresh must be enabled for the ZENWorks Agent.
