Hi,
I've been using SMEServer 7.2 on an ordinary pc (pentium IV, 256 ram, intel mainboard) for about a year now. I use it as a web server that hosts only a school intranet based on Drupal 5. It used to work well with no interruptions at all for about six months. Then, it would start to crash every now and then. What I would get on the screen would be something like this:
-process kswap
-stack
-calltrace
-<o>fatal exception: panic in 5 seconds
-kernel panic-not syncing:mm/swap.c329
-spin-lock(mm/page-alloc.c:c036e9c8)
-already locked by mm/umscan.c/665
I could only find on the net that problems like this are due to hardware problems. I reinstalled SMEServer, hoping it would fix the hard disk, supposing it was damaged. However, it still fails, but what I get on the screen when it crashes is like this:
[<c031b9c>]common_interrupt

[<----sth-->]ret_from_fork
[<----sth-->]autoremove_wake_function
[<----sth-->]kswapd
[<----sth-->]kernel_thread_helper
I can't understand any line of it. I hope you do.
So, is it a hardware problem? If so, what kind? Is it because the pc is not powerful? How can I tell what's wrong?
Thanks so much for your help.
