Hello,

we run a server with Fedora 8 and SRSS 3.1.1. Sometimes (approx. once in a month) it happens that SunRay sessions are disconnected overnight and no login screen appears. I looked in /var/log/messages and I found these suspicious lines:

When someone tries to log in at the system console s/he gets a message about X crash. The X server recovers afterwards, but gdm is only running on display :0.

Today, I managed to fix the server by sending the server to runlevel 3 and then to 5 again, but last month this didn't help and I had to rebbot the server.

My questions are: what's causing the crashes, how can I prevent them, and what is the propper way to recover the SunRay server?
