Kevin,

Thanks for your input. I tried doing the sort to see what was being
written where most and got this resut:
bash-3.1# du -k | sort -rn | head
16352   .
11258   ./db
9625    ./db/pkg
2698    ./log
1245    ./backups
750     ./spool
660     ./spool/clientmqueue
614     ./backups/etc
607     ./backups/work
396     ./db/pkg.refcount
bash-3.1#


It looks like my db directory is the culprit. This morning a releated
problem was because var was > 50% full, postfix started complaining with
error 452.

I have currently set min_message_size=750000 and min_queue_free=2024000.

My question is to avoid further var being full problems, is there
something I can do to set the /var/db to point to another slice?

Thanks,
