[sr-dev] [kamailio/kamailio] Issue with usrloc 'handle_lost_tcp' and dmq_usrloc 'usrloc_delete' (Issue #3479)

### Description When a TLS connection is closed and handle_lost_tcp=1 the entry is deleted for usrloc. This deletion is not synced via DMQ even though usrloc_delete=1. There is also an issue on the same server if a re-registration happens right after before the timeout was supposed to expire then $var(sv_res) = 2 even though the usrloc table is empty. So it seems like the way handle_lost_tcp deletes is not deleting fully in registrar. usrloc db_mode is 0 ### Troubleshooting #### Reproduction Setup 2 servers with DMQ and close the TCP connection. ### Additional Information * **Kamailio Version** - output of `kamailio -v` ``` version: kamailio 5.6.1 (x86_64/linux) d8f98b flags: USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MMAP, PKG_MALLOC, Q_MALLOC, F_MALLOC, TLSF_MALLOC, DBG_SR_MEMORY, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLOCKLIST, HAVE_RESOLV_RES, TLS_PTHREAD_MUTEX_SHARED ADAPTIVE_WAIT_LOOPS 1024, MAX_RECV_BUFFER_SIZE 262144, MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 8MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. id: d8f98b compiled on 19:05:04 Aug 16 2022 with gcc 8.3.0 ``` * **Operating System**: <!-- Details about the operating system, the type: Linux (e.g.,: Debian 8.4, Ubuntu 16.04, CentOS 7.1, ...), MacOS, xBSD, Solaris, ...; Kernel details (output of `lsb_release -a` and `uname -a`) --> ``` Debian 10 ``` -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/3479 You are receiving this because you are subscribed to this thread.
