<br><font size=2 face="sans-serif">We have a system running Python 2.6.6
under RHEL 6.1. A bunch of processes spend most of their time sitting
in a BaseHTTPServer.HTTPServer waiting for requests.</font>
<br>
<br><font size=2 face="sans-serif">Last night an update pushed out via
xcat whimsically restarted all of the network interfaces, and at least
some of our processes died with bus errors (i.e. no errors or exceptions
reflected up to the Python level, just a crash).</font>
<br>
<br><font size=2 face="sans-serif">This is just my initial looking into
this. Seeking opinions of the form, say:</font>
<br>
<br><font size=2 face="sans-serif">Yeah, that happens, don't reset the
network interfaces.</font>
<br><font size=2 face="sans-serif">Yeah, that happens, and you can prevent
the crash by doing X in your OS.</font>
<br><font size=2 face="sans-serif">Yeah, that happens, and you can prevent
the crash by doing X in your Python code.</font>
<br><font size=2 face="sans-serif">That wouldn't happen if you upgraded
S to version V.</font>
<br><font size=2 face="sans-serif">That sounds like a new bug and/or more
information is needed; please provide copious details including at least
X, Y, and Z.</font>
<br>
<br><font size=2 face="sans-serif">Any thoughts or advice greatly appreciated.</font>
