[sr-dev] Kamailio 5.1 nightly (rc2) crashing - udp_rcv_loop(): print buffer building failed

[George Diamantopoulos]

Hello,

I've just installed kamailio 5.1 nightly from the debian repo for stretch.
I didn't change anything in the configuration compared to 5.0.4 (which I
was testing previously), apart from the database structure as found in the
wiki for upgrading from 5.0.x.

Now kamailio crashes after a while, with the following output in the logs:

Nov 29 15:47:05 modcom-sbc-dev1 kamailio[2497]:  3(2502) ERROR: <core>

Let me know if I can somehow help dissect this issue, I don't really know
where to start. Thanks.

BR,
George
