I also see this, both on 6-STABLE and 7-STABLE. I have not tried
8-CURRENT.
This is what I have found so far. After cron has sent the header
information to sendmail and before it sends the body, cron detects a
SIGPIPE and stops further processing of the cron job. (This gives the
size=0 in the sendmail log file.) sendmail then drops the uncompleted
message.
Sadly, I have not had enough time to dig any deeper. I ended up
patching cron to ignore SIGPIPE and this "fixed" the problem.
I really must make some more time to look into this.
Cheers,
Nick.
