90%cpu

[Chris Hanlon AMA]

On Friday I accidently deleted the /var/qmail directory (well actually my
package manager did(I didn't realise qmail was taged for remove)).  I
restored qmail from a backup cd (several months old) and found out that
long file nams were lost.  I went to the qmail src directory and types
make setup check.  Anyway qmail-send is now using over 90% (60% system,
30% user)  of the cpu (on a celeron 366) even when there is nothing in the
queue.  Before Fridays incedent it used under 1% of the cpu.  Any ideas?
