Comment 1 Matthias Welwarsky 2009-03-12 17:59:25 UTC

file descriptor leak?
You might want to check with lsof, or have a look at /proc/<pid>/fd directly

Comment 2 Edmon 2009-03-19 06:05:41 UTC

Created attachment 32251 [details]
List of files opened by digikam

17321 being the pid of digikam:
$ sudo lsof -p 17321 | wc -l
1136
