Dear Experts,
Lately we have been facing a 503 - Service Unavailable error in SXMB_MONI.
The symptoms that I've observed is started from the Adapter Engine becoming slow (Java Part). Because when I go to the RWB, message monitoring, choosing the Adapter Engine from the component takes more time than usual.
After sometime that the adapter engine is processing slowly, the messages in integration engine become stuck in SMQ2, trying reprocessing the message ends up with 503 - Service Unavailable. Sometimes it is ICMP service unaivalable.
We then solve this problem by restarting the PI system.
What I want to as is. What is this 503 - Service Unavailable error? Which part should I check?
Is there any tools that can be used to monitor the Java stack of PI? Can we use SolMan? Like the utilization, etc...
Thank you,
Suwandi C.
