[OpenAFS] bosserver cron and signal 13

[Nathan Neulinger]

Here we go... I knew I had this somewhere...

---------
Subject: 
       TR-60933: vos backupsys failures with SIG13/SIGPIPE

Just wanted to let you know this problem has been corrected.  The
following
delta addresses this issue:

somkar-12625-afs3.5-vos.backupsys.fails.as.bos.cron.job

At this point I'm not sure if this fix will make it into the next 3.6
patch
or not.  However, if you'd like, I can give you some new bos/bosserver
bins
that you can test out.  Just let me know.

That was from 5/1/01.
