Hello networkers,
We have a strange issue that currently happened at our router.
information:
OS : FreeBSD 4.11-STABLE #1: Tue Jun 7 19:21:04 WIT 2005
Routing Software : quagga-0.98.3 (compiling from ports)
Network: Running eBGP (with full international route 16k prefix)
1 Neighbor, route about 6-8 Mbps traffic.
here's the issue:

is there any suggestion? we're just having a plan to increased the
the amount of memory tomorrow night from 512Mb to 1G.
but for sure this router have been quite stable for about half year
without any problem. not sure though whether its quagga or freebsd
issue.
