Does anybody know how to find out what process makes use of high load CPU utilization on DP?
When I updates configuration, CPU usage increased from 5% avg to 50%.
I added new xml manager with load balancing group and default other settings, LBG itself with 4 round-robin servers and a new rule for outgoing responses which process response unmodified, just transfer it to the client. That's it! After that CPU utilization increased up to 50% average and 97% in peak. The total load level of the device (I mean incoming requests quantity) didn't changed.
It happened on 4 different devices where upgrade was made.
So I wonder what kind of these changes have caused such a thing?
Can anybody have ideas?

There is not way you can control the no of retries or the timeinterval, hence if there is some issue with the connection, it keeps trying and the db2cli eats up the CPU.

I found out that in my case CPU utilization increased due to using Load Balanced Group. I didn't know that LBG uses a huge amount of CPU resources.
Is there any possibilities to decrease CPU used by LBG?
