Database Agent keep on stopping

hi,

my db agent works fine for a few days then suddenly stopped. no server reboot or whatsover.

 these situation has been going about two weeks. whenever i started the agent, it will keep on running and collectors are collecting data as it should be..but after few days or so.. suddenly on the ui it shows agent stopped reporting. but when i check into the db-agent running process its still running.

 

the only clue that i have from the db-agent was

 

[AD Thread-Metric Reporter1] 23 Oct 2017 13:40:25,378 ERROR ManagedMonitorDelegate - Error reporting metrics
java.lang.OutOfMemoryError: GC overhead limit exceeded

 

but i have already provisioned 4gb as max heap to the agent...i dont know if that is the case..some1 help please

Hi Razzi,

 

It looks as if your GC (Garbage Collection) is the issue. I recommend looking over this doc to see if it might help you remediate the problem: https://docs.appdynamics.com/display/PRO43/Garbage+Collection

Newer version of the above Appd Docs page: https://docs.appdynamics.com/display/PRO45/Garbage+Collection#space-menu-link-content

This is also a good resource: http://www.baeldung.com/java-gc-overhead-limit-exceeded
