I just experienced a pseudo denial of service issue. A server of ours runs woody and bind seems to have filled syslog and daemon.log with about 1.3g worth of messages along the lines of
Apr 18 18:25:38 server named[241]: sysquery: no addrs found for root NS (A.ROOT-SERVERS.NET)
Apr 18 18:25:38 server named[241]: sysquery: no addrs found for root NS (B.ROOT-SERVERS.NET)
Apr 18 18:25:38 server named[241]: sysquery: no addrs found for root NS (C.ROOT-SERVERS.NET)
This in itself was not much of issue except that logcheck started to eat up all the memory and the kernel starts to kill processes.
What I have done is to recreate syslog and daemon.log with the above lines stripped out with grep and restarted the the logging daemons. However, I would like to know how to prevent something like this from happening in the future.
Any help / pointers in this matter will be appreciated.
Thanks and best wishes,
Shri
