Hi,

One of our SuSE11 SP1 VM hung last week. We were uanble to ping/ssh the server. Also not able to access the login prompt at the console.
So; we decided to restart.

However we are not able to find any clues in the /var/log/messages file on what caused the server to hang / not respond.

From the /var/log/boot.msg we can see that the server boot started at 14:38. However before this time or after it; we don't find any clues on what caused the server to hang / not respond. Please comment or point us in the right direction.

**** excerpts from /var/log/boot.msg ****

Boot logging started on /dev/tty1(/dev/console) at Fri May 27 14:38:53 2016
