Hi folks yesterday I did a yum update on my FC4 system to bring it up to date. Since then my system has ground to a virtual halt 4 times and I've had to press the reset button to get things going again. The problem is it's my box is my mail/web/SQL server and it's causing problems. The load isn't excessive and hasn't changed in ages, so I'm guessing it's the upgrade that's caused the problem. I did fine the following in the syslog immediately before the reboot. Anyone got any ideas?
