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 ?
Thanks,
Marek Kroemeke
