Symptoms

Daemons that read statistics will leak memory over time so the amount of memory they use will continue to grow.

Impact

Eventually the daemon or system could run out of memory.

Conditions

There is an error reading a statistics file. For example, a junk file could be copied to /var/tmstat/cluster, or permissions on the file or directory prohibit access.

Workaround

Remove anything causing an error reading a stats file such as deleting junk files or fixing permissions.

Fix Information

The memory was freed along certain error paths.
