Ken, what is mean "active client" - cluster nodes, concurrent jobs or so?
We had issue with buffer size and when we have increased it to 4MB
problem was gone. But this value isn't related to anything so I'd hope
to know how to calculate right IPC buffer size.
Our cluster has nine nodes and about 80 pacemaker_remote members, so
what IPC buffer size I should set?
