    Hi guys, I have a strange problem. On one of our servers the FTP and POP services will just arbitrarily fail. I have a feeling someone is doing something naughty but I wanted to get some input as to where I should poke my head to find out what is going on the box.

    The server is a Dell dual Xeon with 2 GB RAM. Plenty of resource to go around so I can't imagine it is out of resources.

    I just had a similar problem with ftp & pop3 failing. the load on the server was reaching 20 but only for a short period. ftp & pop3 seem to be the first to fail when the load is high.

    I found the cause to be a bad mysql database using too much cpu and mem.

    don't know if this is the same reason yours are failing. Check the logs and see who was doing what at the time of the failure.

    mytop is a good script for catching mysql users

    Go on, have a guess
    One thing to check is that you're not using SIM from rfxnetworks which conflicts with chkservd and can wreak havoc.

    I had same problem.. loads were over 20 because of huge traffic in one site using MySQL. I stopped MySQL for a while and restarted FTP and it came back up.
