As far as sendmail is concerned, this is a pretty serious problem. This could be the fault of a kernel that is not configured sufficiently well to properly host the mailing list. You may need to edit your kernel definitions, recompile and relink it, then reboot. This may need to be done several times, in order to find a suitable value for this number. You may be lucky enough to find that this value can be tuned interactively, without actually rebuilding the kernel.


Or, this could be the fault of processes grabbing too many locks and not releasing them. In that case, the only thing you can do immediately is to reboot the box, but the misbehaved programs should be found and fixed or you'll just have to go through this over and over again.

      Which seems to be the end of it - except that mail man would
 not let go.  I let it run 15 minutes the second time, to see if it
 would die on it's own.

Mailman should not let this go, but then it also should not be re-trying so quickly. It should schedule a re-try later, and give the system time to recover before the next attempt. This re-try timeout should be measured in terms of minutes or hours, not seconds or micro-seconds.



Unfortunately, I'm not sure I can provide any further assistance on this subject. I don't know your OS (I've done most everything but Linux), and I'm not a programmer (so I can't get down in the guts of mailman).
