[OpenAFS-devel] Leak in fileserver?

[Nathan Neulinger]

Any idea what might be causing this? We saw some fileservers sucking
large amounts of memory, and then this result in afsmonitor, note the
huge number of connections (numclients). 

There was also a warning in the logs: 

Sep  4 14:15:47 afs2 fileserver[1008]: ****Allocated more volume
headers, probably leak**** 

Any idea what might be causing this? Only thing special about these
servers is that I have them configured with relatively large inode-max
(512000) and file-max (256000) and ulimit -HSn set to 16384.

Restarting the fileservers caused the performance issue and memory
utilization to drop back to something reasonable.
