Hi all! We trying to use two instances of kamailio on FreeBSD, kamailio was build from master branch. If I enables DMQ, 2 threads (pids) start utilize CPU, less than minute it's up to 100% (on a both servers). At that time kamailio successful handle calls, dmq and usrloc replication wokrs fine. While trying to understand what happens I got this debug info - something happens and K. cycles on shed_yeld() func. All additional info I put into attachments: [gdb_output.txt](https://github.com/kamailio/kamailio/files/528881/gdb_output.txt) [kamailio.log.gz](https://github.com/kamailio/kamailio/files/528879/kamailio.log.gz) [kamailio.txt](https://github.com/kamailio/kamailio/files/528883/kamailio.txt) [kdump.txt.gz](https://github.com/kamailio/kamailio/files/528880/kdump.txt.gz) [ktrace.out.gz](https://github.com/kamailio/kamailio/files/528878/ktrace.out.gz) [top_output.txt](https://github.com/kamailio/kamailio/files/528882/top_output.txt)
