Description Radim Hatlapatka 2014-07-21 08:51:37 UTC

Describe the issue:
There is no section which would describe common troubleshooting solutions which are not specific to any of the subsystems.

As an example can be that customer will start experiencing OutOfMemoryError - unable to create new native thread. This can be caused by having set limits for number of processes to low number. (This can happen e.g. if you are doing lots of managment operations at once (e.g. using CLI), memory limit for GC is not hit in order to clean the threads before hitting the limit for number of processes)

Solution would be to increase ulimits for number of processes.


Suggestions for improvement:
Add section containing useful troubleshooting information such as the one described above.
