>Description:
This machine is used as a FTP/HTTP/RSYNC server. The programs used for these
protocols are: in-tree ftpd, mathopd, rsync.
The machine has a quite fast internet connection (Gbps), but it's limited
by its Intel PRO/100 card (fxp).
After running some hours with a moderate load (50-80 Mbps traffic) the
machine crashes.
I've attached the related gdb, dmesg, and the kernel config output.
This machine works very stable with RELENG_4, but I need 5.0 because of the
>How-To-Repeat:
Just install a FreeBSD 5.0 on a busy FTP server...
>Fix:
If I would know...
