Jeff,
Do you have your pqact split across multiple files? Each pqact process
can only take up 32 child processes, so if you have a busy system, pqact
will wait for "slots" to open up before it can start a new write or
process. So I do something like this in ldmd.conf
exec "pqact -p BZIP2/K[A-D] -f CRAFT etc/pqact.CRAFT"
exec "pqact -p BZIP2/K[E-H] -f CRAFT etc/pqact.CRAFT"
exec "pqact -p BZIP2/K[I-K] -f CRAFT etc/pqact.CRAFT"
exec "pqact -p BZIP2/K[L-O] -f CRAFT etc/pqact.CRAFT"
exec "pqact -p BZIP2/K[P-R] -f CRAFT etc/pqact.CRAFT"
exec "pqact -p BZIP2/K[S-Z] -f CRAFT etc/pqact.CRAFT"
exec "pqact -p BZIP2/[NTP] -f CRAFT etc/pqact.CRAFT"
Notice how the regex splits up the processing, eventhough I use the same
pqact config file in each.
