F4.9R: kernel trap, reason?

[Jimmy Scott]

Hi, this evening a complete webserver (including mail/mysql/dns/pop3) went
down,
can tell me what exactly happened here? or how i can find more information
about the crash
(except inspecting the default files in /var/log/)

/var/log/messages right after the reboot (last message was an ftp upload)
