fix for one crash! Re: [Pdns-users] 2.8 / 2.9 signal 11 problem

[A/S ScanNet - Dan Faerch]

My servers suddently started crashing wildly as well today..

The pdns is chrashing 5-6 times a minute on both.. Its wierd, course i didnt
have any problems until today, and i upgraded to 2.9.8 the same day as it
was announced (i think)..
After a '/etc/init.d/pdns restart' they went bazerk..  I tried uninstalling,
reinstalling, recompiling ect.ect.. nothing worked..

I succesfully downgraded both servers to 2.9.7 and everything is running
normal again..
