Hi Wolfgang,
What version of geoserver are you using? There are known memory leaks with
the WFS subsystem in released versions, but if you grab a recent nightly
they should be no longer.
Are you using WFS at all? Or just WFS?
What are your current memory settings? If you want to do some debugging what
you can do is limit the heap size to something like 1G and then add
the -XX:-HeapDumpOnOutOfMemoryError
which will dump the contents of the heap when the server runs out of
memory.
Then you can try to use a profiling tool to analyze the dump to figure out
where the memory leak lies. Or if you can make the dump available another
dev might be able to download and analyze it.
