Description Jakub Hrozek 2017-08-16 21:07:06 UTC

This bug is created as a clone of upstream ticket:
https://pagure.io/SSSD/sssd/issue/3465

I was working with lslebodn on IRC (freenode #sssd) and even after installing the latest LTM release 1.13.4 on EL6, sssd_be is leaking memory on systems with enumeration disabled and regular lookups going on. lslebodn mentioned: quick check of the valgrind log and it seems that 33MiB are leaked in cyrus sasl code

I have this issue on both EL6 (6.9) and EL7 (7.3). Attached is 2 hours of valgrind output of SSSD version 1.13.4 running on EL6. sssd on this server was last restarted on the evening of August 4th (less than 4 days ago) and sssd_be is currently using 125MiB of memory.

Comment 2 Jakub Hrozek 2017-10-04 20:09:45 UTC

In all the testing we've done the increase seemed to have stabilized after some time which might be due to e.g sssd connecting to other domains or discovering more servers. We could never prove an ongoing leak, therefore I'm closing this bugzilla.
