We have encountered OutOfMemory error Java heap Space. Confluence hangs or behaves unexpectedly not accessible. the atlassian-confluence.log contain an error message like:
Caused by: java.lang.OutOfMemoryError: Java heap space
Our Current config on the setenv.bat is like this.
set CATALINA_OPTS=-Xms1024m -Xmx1024m -XX:+UseG1GC %CATALINA_OPTS%
Since when are you facing this issue ?
At what time you encounter this error ?
How often you have encountered this issue ?
Do you suspect any operation which might have caused this ?
! GB heap comes by default (consider it as a setting suitable for evaluating Confluence) , however as the instance grows you might need to increase the heap size.
There are various factors which may cause a out of memory error.
Newly installed plugin , some memory hungry operation , increased usage , etc
In your case I would recommend increasing the memory to 1.5 GB and observe how the instance behave.
If you still face issues. increase it to 2 GB .
If you still face the issue it might be possible that something is causing a memory leak. And you will need to investigate further.
Thanks for the quick reply.
Since last Sunday Afternoon and yesterday around 6pm. then I decided to investigate what cause the downtime, and I find the error java heap space,.
I just want to ask if is okay to increase the memory to 1.5GB from Confluence 6.0.1 version. is this compatible.
