    Hi,

    i have a some questions, because i can not find out some solution for this, maybe here you will can help me.

    We have problems with servers (Fedora 6 / x86_64) , they are freezing and we can't understand where is the problem. sometimes in the logs we get messages like this:

    We get this kind of messages. we tested for bad rams and rootkis, everything is ok. And the main problem is that when the server is frozen, it doesn't logged what is happening after restart, we can't see what is wrong.

    What can we do in this situation, how to understand which aplication make the problems with out-of-memory?

    There writes killed mysql or irqbalance, but sometimes i suppose this is not right, or maybe i'm wrong...

    I hope that you will help me to solve these problems

    Thanks in advanced!

    Not sure what happens, but do you use a monitoring solution like munin? It produces graphs of everything on your server - maybe you can see then what the problem is.

    thanks for the tip.

    i know that the problem is with postgresql and mysql, i will try to make better configuration. i installed monit in one of the servers. i suppose it will help me to solve this kind of problems with critical aplications
