2. Also ps command shows "winbind" memory consumption increased over the time.
Looking for fix or backport of fix from newer samba.
This might be related or even a duplicate of https://bugzilla.redhat.com/show_bug.cgi?id=1364363.
We need valgrind logs with debuginfo packages installed. samba-debuginfo, libtalloc-debuginfo, libtevent-debuginfo, libtdb-debuginfo ...
Stop winbind and then use:
valgrind --tool=memcheck -v --num-callers=20 --trace-children=yes --log-file=/var
Created attachment 1265750 [details]
I'm sorry, but the valgrind log has been created without samba3x-debuginfo packages installed so the information I get are very limited.
However the only issue I see is inside of the openldap library which calls close() on an -1 fd.
Also I see only the log from one winbind process. Winbind normally has more than two processes.
