Hi.

Look at this (you can try youself, i wont reboot it for  a few days):
PING 164.8.233.107 (164.8.233.107) 56(84) bytes of data.
64 bytes from 164.8.233.107: icmp_seq=1 ttl=64 time=8366 ms
64 bytes from 164.8.233.107: icmp_seq=2 ttl=64 time=7367 ms
64 bytes from 164.8.233.107: icmp_seq=3 ttl=64 time=6367 ms
64 bytes from 164.8.233.107: icmp_seq=4 ttl=64 time=5367 ms
64 bytes from 164.8.233.107: icmp_seq=5 ttl=64 time=4367 ms
64 bytes from 164.8.233.107: icmp_seq=6 ttl=64 time=3367 ms
64 bytes from 164.8.233.107: icmp_seq=7 ttl=64 time=2368 ms
64 bytes from 164.8.233.107: icmp_seq=8 ttl=64 time=1368 ms
64 bytes from 164.8.233.107: icmp_seq=9 ttl=64 time=368 ms

This is the third time, and i don't know how to reproduce it. Some uptime
seem to help (between 13.2 days and 14.5 days in this case).
It's not heavily loaded, serves mainly as ftp server on 100 mbit LAN.

Anything i can try, to help resolve this? (Preferably not something that
involves rebooting, because it can take months for this to happen again)
