Mono
We have had an issue (https://sourceforge.net/apps/mantisbt/openpetraorg/view.php?id=107) where the OpenPetra server crashes after a while, running on Mono, due to growing need for memory and running out of memory eventually.
See this article: http://www.mono-project.com/Performance_Tips#Using_the_Mono_profiler

to get the process id, type
ps -A | grep mono
result:
7220 pts/0 00:00:25 mono
then display the current memory usage:
ps up 7220
result:
USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND me 7220 20.6 4.6 93704 36744 pts/0 Sl+ 11:42 0:25 mono --server -
Add --profile=default:alloc to the mono call in your openpetraorg-server.sh. then in the long result, look for "Allocation profiler" heading
