Hello,

I recently upgraded to centos9 and I'm seeing quite a few cache files marked deleted under /var/lib/sss/mc. According to lsof, the majority of them are owned by bash processes but they were originally spawned by sshd. I've tried adding SSS_NSS_USE_MEMCACHE=NO to the environment of the sshd daemon, but that doesn't seem to help. The partition on which the cache files reside is only 1G and it does create a problem when the number of ssh sessions is large. Currently there are ~140 such deleted files with unique i-nodes.

The version is I'm running on c9 is 2.9.4-7. Same version was running on this host on c8 where this issue didn't occur though I didn't ever look there because there were no alerts on the space usage. So I assume it wasn't an issue.

Is there something that can be done to improve the situation?
