2 PC Linux server, hangs with kernel panic.
I have a problem with 2 RedHat installed Linux PC's.
Oracle cluster software is also installed on both machines. They both work on (the same) SAN.
Problem is that weekly, at exactly the same time the server, so both PCs, hangs.
The only thing I see is kernel panic on both PC's (--> flashing lights on the keyboards).
The only thing I can do is manual rebooting the machines...
After reading several articles on this forum I read 2 things:
dmesg > /tmp/kernel.panic.txt
should give me info on the reason what the kernel panic causes? Can I use this after manual rebooting?
To see what is happening at the very last moment before the server hangs use the top command.
How can I log ALL info from top in a file, so I maybe can see what's happening just before the server freezes?
Anybody any experience with these possibilities
Could the hangcheck-timer be the reason for freezing the server?
Thanks for helping. I've no ideas anymore...
