My 5.64 runs out of file descriptors when there is lots of mail
queued up for a host which has been unreachable for longer than
three days (my timeout).  It happens to the process running the
queue when it tries to return mail to the sender.  The senders'
addresses all resolve to the same mailer.  After it successfully
returns mail to several of the senders, it is stopped dead in
its tracks with something like this:

Dec  8 19:11:32 cs sendmail[16583]: AE16583: SYSERR: queueup: cannot create temp file tfAE16583: Too many open files

Anyone know the cause of this?
