There is a new record, a load average of: 29.29.
Total accounts in /home/spool/mail/ is 536, about 260 accounts are forwards
though....
Why are there qpoppers from root? This mostly seems to happen when inetd is
restarted but that isn't the case and why do they take that much CPU (he
record I have seen is one qpopper with 86% CPU)?
It allmost seems like the interpretation of the CPU% and the CPU-load is a
"little" bit off.
