[ovirt-users] Ovirt Hang after adding to ManageIq

[Liran Zelkha]

It should decrease the GC frequency and reduce the CPU time.

Thanks for reply.

I can increase Heap size, but does it resolve CPU hogging problem.

The engine is configured by default to use 1GB of HEAP. It won't take more 
than that, so it won't show as using too much memory on the system 
monitoring.
The engine log mentions OutOfMemory errors caused by excessive GC, and the 
Exceptions that follow are related to OutOfMemory situations - so 
increasing the HEAP size should assist you.

Thanks for reply.

What I observed is Manager is not consuming much memory, Only CPU usage 
going high.

Hi Chandra,

You have OutOfMemory errors. In Java applications, this causes allot of GC 

activity, which causes CPU usage to spike.
Can you allocate more memory to the oVirt engine?
