Hello,
I've tried to find out the cause of some strange resolving problem we
are experiencing. From time to time, our server seems to ignore some
requests, while others are answered promptly. It seems to me that the
problem is UDP packet loss.
Udp:
948795842 packets received
149802 packets to unknown port received.
214635022 packet receive errors
1003702082 packets sent
I've tried to increase system udp receive buffer 10x and then 100x with
no noticable effect. Do I have to change something in Bind, too? Or am I
completely wrong?
RedHat Linux ES release 4, 2.6.9-34.ELsmp kernel, dual Opteron system
with 6GB ram, no local zones, just resolver/cache. bind-9.3.2-2_EL4
Thanks!
