Hello,

Over the past few days, the OpManager server is having some performance issues (the java process works around 65%) and the web gui takes a lot of time to respond. 

The logs show the following exceptions:

- java.lang.OutOfMemoryError: Java heap space

- org.postgresql.util.PSQLException: An I/O error occured while sending to the backend.

- java.lang.NullPointerException

This issue occurs after We created two dashboards to monitor firewall and APC device. This dashboards are used from two different CCTV views and displayed on three PC every 5 minutes. The only work around is the OpManager server restart, at the moment.

Could you help us on this?

Let me know if you need other information.

Thank you in advance.

Kind regards.

Fabrizio
