    Subject: FC1 Killing processes

    I'm running FC1 on a intel 1.7G CPU with about 700MB RAM.
     
    We get the following in the DMESG were precesses are killed. This is a small
    mail server serving about 3k messages a day. We run MailScanner SA sendmail
    and Virus Checking.
     
    My logs are supposed to be updated to a MYSQL DB but I had to stop this for
    my server kills mysql and then everything stops. We aslo had a chaching DNS
    but this was also killed.
     
    The server starts fine and runs for a while then it starts killing
    processes. This server run OK until we loaded fc1. Previously we were
    running RH9
     
    Where can I start looking for problems.
     
    This is wat I got out of /var/log/messages

    Hi,
    Output from top and vmstat would be helpful to troubleshoot, sort top by
    memory usage (shift-M) will probably give you some idea which process is
    taking all of the available memory.
