Subject: tcpserver causing reboot?
Date: 18 Mar 1997 18:50:32 -0000

Russ,

NS has rebooted twice today. The logs indicate that tcpserver was involved
both times.:

Mar 18 08:27:16 ns vmunix: pid 13355, `tcpserver': Data access exception
Mar 18 12:59:46 ns vmunix: pid 3194, `tcpserver': Data access exception

Full logs below.

Any ideas as to what is going on?

- -Dave
