BUG: unable to handle kernel paging request

English Applications
#1

Hi,

My apologies if I’m posting this in the wrong place. I’m an email administrator (Lotus Notes) limited Linux skills who has inherited a 10.2 server that crashes a couple of times a month. There’s stuff all over the Internet with the exact error message, but the issue seems to differ depending on what distrib is being used, and I can’t find the issue in these forums so hopefully someone can point me in the right direction. The result from the messages file follows, any help interpreting it would be much appreciated:

If you really think that this is a bug, please do not post it here. Instead, please take a look at this page to find out where and how to file a bug for OpenSUSE. Welcome to our Forums! :slight_smile:

Thanks, but I don’t know whether it is a bug or not, that’s just what the error says (as per the first line in the screen dump). The info I’ve read on it so far has had people stating that it’s a kernel error, or faulty RAM, or faulty disks, or just faulty hardware and to take everything out and replace it one by one until the issue occurs. I’m trying to work out how to narrow it down first without having to pull apart a production server to try to work out what the problem is.
