oacore crashing after 12.2.9

[chenthil]

Hi,

We are running on VM on vmware on 12.2.9/

After the upgrade we are continuously seeing oacore cpu spike to 700 and 800%.

How do we trouble shoot for the root cause.

Thanks

Hi,

Please answer the questions below;

What did you upgrade?
In which layer is CPU usage increasing? (in DB or Apps nodes)
What is your OS?
