kswapd killing server
Hi,I am helping a friend addesing an issue with one of his servers.
The server seems to go down once every hour or so.
I managed to get a copy of top output from server before it froze:

After server hangs, it sometimes comes back up in 15-20 mins and some times need a hard reboot.
It seems to me that it is kswapd causing this?
Any suggestions on how to track the problem down?
