>Description:
3 servers (same kernel config and release) connected via a gigabit switch are producing terribly latencies which make the web/database servers unusable.

192.168.10.2 is a DB server but the traceroute shows incredibly latencies:

1. 192.168.10.2 0.0% 80 4.4 95.6 0.6 1003. 194.5
This happened when upgrading from 6.2-Pre release to 6.2-RELEASE. All servers are affected.
>How-To-Repeat:
Reboot the server and do mtr (mytraceroute) to 192.168.10.2, which is 1 hop away.
>Fix:
Rollback to 6.3-PRE RELEASE? This there a CVS tag for this??
