Java memory error

fresh-it

Hello,

We've started getting an errror stating: "java.lang.OutOfMemoryError: Java heap space". I've tried to increase the JVM using instructions from this article, but it doesn't help. I've also read that clearing the JVM heap memory could help and this is done by restarting, but even after restarting we get the error after 5-10 minutes of use.

Below is the stack trace, any help is greatly appreciated. We're running WHD version 12.1.0.300

We're sorry, an unexpected error occurred:

java.lang.OutOfMemoryError: Java heap space

A bug report has been e-mailed to SolarWinds.

If this is a sudden and new issue and there have been no major changes to your environment otherwise and your sure the server or VM itself is not out of memory you should probably open a ticket with SolarWinds support. Also please note 12.1 is no longer supported and 12.2 is only supported until November of 2018 so an upgrade to at least 12.3 or higher may be necessary.
