Hello, I had a similar situation on a 1812 running 12.4(11)T with dns spoofing enabled and while I was searching at the release notes I saw that a lot of new functionalities where added in the DNS process on 12.4(11)T. eg. dns views. I disabled spoofing, downgraded to 12.6T6 and everything looks normal.
I think I had seen also a few bugs in the bugtool about the DNS process. look for example: CSCsg64586 --koug Skeeve Stevens wrote: > Can you please tell me if there is a specific reason/bug for this? > > The router was running 12.4(6)Tyy and was still doing this, before I > upgraded it to 12.4(11)Txx to try to fix it. > > ...Skeeve > > -----Original Message----- > From: John Kougoulos [mailto:[EMAIL PROTECTED] > Sent: Tuesday, 17 April 2007 2:19 AM > To: [EMAIL PROTECTED] > Cc: 'Cisco-nsp' > Subject: Re: [c-nsp] Cisco 1811 DNS Server overload > > also if you are using 12.4(11)Txx, consider moving back to 12.4(6)Tyy. > > > Skeeve Stevens wrote: >> I have an 1811 temporarily doing NAT for about 200 clients and at the > moment >> and while it generally is working ok, the DNS facility of the router is >> freaking out. >> >> Some show logging: >> >> *Apr 16 11:55:53.425: %SYS-3-CPUHOG: Task is running for (2000)msecs, more >> than (2000)msecs (13/0),process = DNS Server. >> -Traceback= 0x8099C694 0x80AB26B0 0x80AB5DB0 0x80AB6834 0x80AB7ACC >> 0x800D7ACC 0x800DB410 >> *Apr 16 11:59:59.721: %SYS-3-CPUHOG: Task is running for (2000)msecs, more >> than (2000)msecs (30/0),process = DNS Server. >> -Traceback= 0x822F21DC 0x8099C78C 0x80AB6508 0x80AB7ACC 0x800D7ACC >> 0x800DB410 >> >> And yesterday it crashed: >> >> Router uptime is 1 day, 2 hours, 42 minutes >> System returned to ROM by error - an Illegal Opcode exception, PC > 0x83B1A8E4 >> at 20:17:29 AEST Sun Apr 15 2007 >> >> I would like to actually stop the 1811 caching DNS queries but I can't >> figure out how to.
