hi

We have gerrit server 3.2.3 we get :
java.lang.OutOfMemoryError: Java heap space

and the server got stuck (crash) - is there something that can be done to avoid future cases like this ?

thanks

Guy

You need to enable the JVM GC log [1] and see why the heap is collapsing. Does that happen on a regular basis?

You can increase the heap size in gerrit.config using
container.heapLimit

Does that happen on a regular basis - No

will check the option of increase the heap size in gerrit.config using.

is there any suggestion for configure the heapLimit ?

Machine Memory and more ?

You need to enable the JVM GC logs to understand what is the problem with the current heap size.

Rising to an arbitrary value won’t help unless you know how much you really need or what is the issue.

There are cases where the problem isn’t actually the size but rather how it is allocated and used (e.g. humongous objects) and therefore the solution could be different.
