     It exits on signal 6.  See the tail end of the log excerpt I included
in my posting about 0.4.6.1-alpha being very noisy.  N.B. 0.4.5.7 also has
the same bug.
     I have browsed a bit in the consensus documents, looking for relays
running those versions of tor.  What I found was that the ones running those
versions on LINUX systems often have much longer uptimes, but I didn't find
any FreeBSD systems running them with uptimes much over one day, which is
consistent with them failing in short order on FreeBSD systems.  I did not
look for those versions on the other BSDs, but such systems are generally
much rarer than those on FreeBSD, except perhaps for MacOS.

     Possibly, but probably not.  Take a look at the crash messages that
tor usually writes to its notice-level log, which look like they have
something to do with authority code, but we, of course, do not run authority
relays.  I think I did have one crash that did not write that batch of
messages to syslog, but usually it does.

     I posted such in my previous two postings.

     xplato's relay may differ from mine, but mine isn't using much these
days because the authorities have a) stopped giving mine an HSDir flag for
the last two months or so after giving it seemingly randomly for months
before that, and b) been giving or withholding a Fast flag seemingly also
at random.  This is on a relay that often runs at 300 KB/s to 400+ KB/s, both
in and out.  The whole mess makes me wonder whether it's worth my bothering
to maintain and run a relay anymore.
     Can you tell us why the consensus documents on Sunday showed *all*
authorities with Bandwidth=20 Unmeasured=1 for some hours?  What caused such
an alarming situation?
