"signal 6" means that the cleanup daemon logged a "panic" message
that specifies the cause for aborting.
Apparently, you are using a syslog implementation that logs different
severity levels to different files. I suggest that you search for
lines with "panic" in all email-related logfiles.
By the way, this means that NO MAIL IS LOST. The SMTP client did
not receive an SMTP acknowledgment, and will resend.
