I'm operating a little storage server on debian, over the past months I've noticed the process udisks-daemon eating up almost all available memory.

Is this just really aggressive caching or a memory leak?

This does not seems to be aggressive caching. It seems to be a bug as per the Ubuntu/Debian forums for excessive resource usage by udisk-daemon. –  PratapSingh Dec 31 '12 at 13:47
    
Can you point me to some threads at the forums? My google search didnt yield any results. –  Harrald Vorreitner Dec 31 '12 at 14:37
