ccsmagtd.exe & ccnfAgent.exe spike CPU and memory on Citrix servers.
Errors seen in the logs:
ERROR Timeout when waiting for comstore save operation!
sending of the "hello" message to the DSM manager xxxxxxxxxx fails: SmSend() returned 0x33202, host xxxxxxxxxx
This problem is related to the big size of the comstore on Citrix systems and that periodically a ccnfreportdelta report will is created (per default every 60 min).
csmagtd.exe and ccnfagent.exe will use more memory and CPU time to create a comstore delta report.
To verify that the policy has been applied
Go to the Citrix system under All Computers. Drill down to Configuration->Configuration Policies you should see 'My_Deltareport' under 'Directly Applied Policies'.
On the Citrix system check the output of the command:
ccnfcmda -cmd GetParameterValue -ps itrm/agent/cc -pn deltareport (The output should be '0')
Note: The delta report is only an add on and disabling it does not reduce functionality.
The Comstore is a configuration file that contains information related to Agent scheduling, Agent run, etc,.. and disabling delta-report just stops the comstore from getting updated at regular intervals.
The setting is important in situations, where the agent is running on a Citrix server and large number of users login/logout, which in turn forces the comstore to be updated continuously, spiking the CPU.
