Issue/Introduction

CA Process Automation 04.3.05.

The performance is slow, some changes aren't being saved by the instances, and the operators are taking a lot of time to process.

What we can see is that our server has a usage of 100% of CPU, but as soon as we shut down PAM, CPU resources come back to low usage 1%-5%. 

We already checked DB performance: ok. And we already tuned PAM. I'm attaching log files, and config files that may help in diagnosis.

Environment

Release : 17.3

Component : SDM - PAM

Resolution

Stop the Orchestrator

Delete the activemq messages with the following query in database:

delete from Node0ACTIVEMQ_MSGS where CONTAINER='queue://ActiveMQ.DLQ'

Back up the following folders and then delete the contents:
audit
data
scripts
tmp
work
wrappers

(please note: delete the contents NOT delete the folders!)

Start the Orchestrator
