Public bug reported:
rpc.gssd appears to be leaking a small amount of memory every time it's
used to authenticate a kerberized nFS mount. I can reproduce by
running:
while sleep 1; do mount -o sec=krb5 nfsserver:/remotepath /mnt; umount
/mnt; done
While running this in a loop, you can observe from rpc.gssd's
/proc/<pid>/status file that its VmRSS grows indefinitely, generally by
about 4 kB per mount request. On some of our servers that have a high
turn-over rate of kerberized NFS mounts, we've seen the rpc.gssd process
grow to more than 600 MB!
This happens on lucid with nfs-common 1:1.2.0-4ubuntu4.2.
I haven't been able to reproduce on precise with nfs-common
1:1.2.5-3ubuntu3, but this is still an important bug for lucid.
