Hello,
do you have a backtrace that you can send just to compare with the one
from Bruno?
Also, send the output of 'kamailio -V' to look at compile flags. Bruno
had a custom compile time flag, a matter of that a different memory
manager was used comparing with the default one for 3.1 series. If you
have the default one, it may include more info that can give some hints.
Cheers,
Daniel
