Hello,
did you run with debug=3 in kamailio.cfg? That piece of code is new in 5.1, but executed only when debug is at least 3 (which is for troubleshooting purposes, not for production). Anyhow, I will check a bit that part to see if anything is wrong there...
Cheers, Daniel

OK, so I performed a clean installation on a new debian stretch instance I haven't been able to reproduce the issue so far. Either something changed in the latest nightly, or the fact that I upgraded from 5.0.4 was causing the issue.
The deployment is automated with ansible, so there shouldn't be any deviations in the configuration of the host. Only other difference (apart from the clean kamailio install) should be rtpengine's building, which was performed anew. However, I don't see how that might have affected things (after all, I don't believe kamailio is a build time dependency for rtpengine)...

Oh, I also tried with 5.2.0-dev1 nightly and it also crashes in the same way...

Is there anything special needed with this build on debian stretch? Checked ulimits, disable_core_dump, /etc/default/kamailio, started it as root (-u root -g root), from systemd with user kamailio, with working directory set in command line and in config file, I just can't get a core dump...

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> [core/udp_server.c:481]: udp_rcv_loop(): print buffer building failed Nov 29 15:47:05 modcom-sbc-dev1 kamailio[2497]: 121(2620) CRITICAL: <core> [core/pass_fd.c:277]: receive_fd(): EOF on 26 Nov 29 15:47:05 modcom-sbc-dev1 kamailio[2497]: 121(2620) DEBUG: <core> [core/tcp_main.c:3512]: handle_ser_child(): dead child 3, pid 2502 (shutting down?)
