    This sounds possibly related to the problem I've been experiencing --
we're using Minivend 3.14 on a BSDI box and minivend just stops running
anywhere from once a week to every 5-15 minutes.  It doesn't hang, or crash
and dump the core, it just... disappears.  We have a process to check if
it's running every minute and start it if it isn't, but of course we'd
prefer it just stayed up... I asked about this several months ago and a
couple other people using BSD-types said they had the same problem, but no
one had any solutions, nor did I find any in the docs or archive.  So is
this (the kernel interrupting socket reads) responsible for the trouble?
Has anyone any ideas or solutions to the problem?  Incidentally, it doesn't
seem to hang and then exit; it seems to be running fine and then quit.  Many
thanks!
