Thanks Perderabo but the capture command is also used outside of the model script. Making that sort of change could affect other uses of the capture command. Maybe we can add a switch to it or something. That will take a while to change. Any other suggestions how I could handle this from within the script? Anyone know where I can find more info on how lpsched communicates with the model script?

We have a total of 51 lpsched daemons running. I just have a feeling that is way too much print daemons.

The following elements may be set for the SIGCHLD signal:
ostatus: Exit value or signal
outime: User time consumed
ostime: System time consumed
opid: Sending process ID
ouid: Real user ID of sending process
The following elements may be set for the SIGILL, SIGFPE, SIGSEGV and SIGBUS signals:
oaddr: Memory location which caused fault
The following element may be set for the SIGPOLL signal:
oband: Band event
ofd: File descriptor number
