Description Alexander Kläser univentionstaff 2013-02-11 09:35:59 CET 
During the UCS@school tests (import of 30k users), it seemed that the s4connector did not free its used memory, output from top shows 27.8% of memory usage, although the synchronisation process was already completed:

> 1743 root      20   0  602m 562m 2688 S  0.2 27.8 335:54.03 /usr/bin/python2.6 -W ignore /usr/lib/pymodules/python2.6/univention/s4connector/s4/main.py

BTW, and samba seems to have gone wild:

> 1270 root      20   0 1159m 431m 415m S 68.6 21.3 469:24.55 /usr/sbin/samba -D

→ 68% CPU. Even long after the import, Samba seems to take every few seconds 100% for a few seconds.

How much memory/swap has the system?

Comment 5 Stefan Gohmann univentionstaff 2016-10-11 08:01:16 CEST 
This issue has been filed against UCS 3.1.

UCS 3.1 is out of maintenance and many UCS components have vastly changed in later releases. Thus, this issue is now being closed.

If this issue still occurs in newer UCS versions, please reopen.
