There is a bug in aix 4.3.3 to do with the .indirect segment in a
filesystem that could be a likely culprit perhaps;

Although you will need a logon to view.

Good thought.

Something from experience:  In running a large POP/IMAP mail facility,
we
find (no surprise) that many users configure their email clients by whim
rather than per defined instructions.  Some will set their client to
check for new mail every few seconds, making for a lot of artificial
system activity, packets, interrupts, etc.  Unreasonable access saps
network bandwidth, leaving less for serious activity, like backups.
This can easily imbalance one mail system relative to another.
Depending
upon your mail server repository techniques, spam can make mail spool
files
inordinately busy, making for costly retries during backups; and the
larger
the mail spool file, the greater that cost.  Mail systems are a huge
pain
to run, with high costs relative to the often trite value of the stuff
being so diligently processed by the system.
