Hi,

If anyone is interested furthur details can be forwarded.

This happened on my mail server after 30 days uptime.  XFS is
SGI XFS snapshot-2.4.23-2003-12-01_00:33_UTC with ACLs, debug enabled
SGI XFS Quota Management subsystem

procmail processes started to accumulate stuck in lock_wait, had to reboot.
