[ale] "mailer prog died with signal 13"

[gt1355b at prism.gatech.edu]

Hello,

I've got a problem that's got me stumped.  Looking through sendmail
logs, I noticed I have a big backlog (sendmail -bp reports 34 and
counting) that haven't been delivered because "mailer prog died with
signal 13."

I'm running sendmail-8.8.5 with procmail-3.10 as the local program. 
Any ideas?

later,
chris
