Crash

[Andreas Tille <tillea@rki.de>]

Hello,

I did further investigation in the E250 server crash problem.  I tried
to report here sometimes but got now real help on the topic - so I tried
again.

Short summary:
  I observe randomly crashes of the E250 box.
  After a crash serial console seems to be dead.
  Sun support only tasks with me if I install Solaris :-(.
  (I would give the hardware-checking Solaris-Binary a try if someone
   on this list gives me a hint how to obtain the Solaris libs.  Is this
   a FAQ or hasn't nobody an idea??)

New info:
Because the serial console seemed dead I tried to keep a seyon session
open.  This showed me some more information on the very point of the
crash:

Does anybody have an idea what could be wrong here?  Sending "Break" signal
the box presented the OK prompt and rebootet (with e2fsck of course :-)).
I observed that if I go this way (not switching the box of as I did before)
the crash happens more often (three times today in contrast to once in
about 14 days before).

Any comments really welcome

        Andreas.
