SIGSEGV after some AXFR queries

Rate this Message:
Hi there,
We are having some very odd crashes (SIGSEGV) on one of our servers - we found in logs that each crash always happens 1-2 seconds after there are AXFR requests from one particular DNS server (I doubt that it's a coincidence). -- OS: Linux, Debian Etch Kernel: 2.6.18-6-686 Powerdns-server: 2.9.20-8+etch1 -- Did anyone notice similar crashes ?

Re: SIGSEGV after some AXFR queries

Marek,
Version 2.9.20 is pretty old, so maybe this problem is fixed in a later release. I know that I have seen this sort of problem when bad data was in the database. Maybe you could try validating the data for the zone that is being requested by the AXFR? Just a thought.

Re: SIGSEGV after some AXFR queries

Rate this Message:
Hi there,
Thanks for suggestions. I was trying to find the particular domain that could have some odd data in MySQL - but the problem is that this DNS server seems to send around ~40 AXFR requests in a row - I was not able to find one particular domain in log that would be there before each crash :-/ We've also tried to upgrade it last Friday to the newer version (2.9.21 and then 2.9.22) - but then all replies to AXFR requests ware empty (no error message, no serv fail - just SOA record and nothing else - so I had to fall back. Any suggestions about this one ? Thanks again, Marek bert hubert wrote: > Marek, > > Indeed - both 2.9.21 and 2.9.22 contain important updates to the TCP > component of PowerDNS.

Any suggestions about this one ? Marek, This usually means you have corrupt records in the database - 2.9.21 and 2.9.22 are a lot stricter than 2.9.20 in this respect, and do not silently ignore many errors. Are you sure there is no logging? Just for testing, see if you can run 2.9.22 in parallel and query your SOA records.
