About once a week listserv dies while trying to update some indexes.  It just stops running.  There is nothing in the log to inidicate a problem.   We are running 1.8e on AIX.  It happened when we ran 1.8d also.  I've got a daemon that runs very half hour to catch this sort of thing and reboot, so it is not as big a problem as it used to be.  Sometimes I edit the offending notebook and remove any huge articles.  Strange thing is it doesn't happen every night, so it appears to be random.
