Description Dmitri Pal 2012-12-19 09:10:23 EST

This bug is created as a clone of upstream ticket:
https://fedorahosted.org/sssd/ticket/1730

a user in the #sssd channel reported a valgrind output that led me to find out a glaring memory leak in the new feature we introduced to clean up the mem cache on initgroups calls.

Comment 1 Jakub Hrozek 2012-12-19 11:02:04 EST

To reproduce, set up a large group. Start the sssd and note the sssd_nss memory consumption.

Then run:
for i in `getent group $largegroup | tr ',' ' '`; do id $i; done

And watch the memory consumption grow gradually.

Comment 3 Kaushik Banerjee 2013-01-22 14:03:27 EST

Verified in version 1.9.2-74

Memory consumption on id lookup of every 1000 users in KB is:
After first 1000: 17124
Next 1000       : 23320
Next 1000       : 18860
Next 1000       : 17640
Next 1000       : 20996

Overall 3MB increase in memory consumption.
