[oopscheck] KERNEL DOS attack?
I've been getting this email notice for a few days and after speaking with my provider they said that my server was under a DOS attack. What can I do to stop or prevent this from happening?
Code:IMPORTANT: Do not ignore this email. Your kernel had an Oops! This is the result of bad hardware or a kernel bug. Your system may continue to function as normal, however there is a good chance bad things are happening right now. Bad things include: files disappearing, daemons crashing, complete server crashs, disk corruption and many others. You might want to check your RAM with memtest86 as this is usually the cause of the problem.
