I have reverted back to using mysql for storing presentity records for now. ### Troubleshooting #### Reproduction Starting kamailio with these mod params can re-produce the issue. ``` #!ifdef WITH_PRESENCE # ----- presence params ----- modparam("presence", "db_url", DBURL) modparam("presence", "server_address", "sip:EXTERNAL_LISTEN_IP:EXTERNAL_UDP_PORT") modparam("presence", "subs_db_mode", 0) modparam("presence", "publ_cache", 2) modparam("presence", "clean_period", 40) modparam("presence", "max_expires", 3600010) modparam("presence", "enable_dmq", 1) # ----- presence_xml params ----- modparam("presence_xml", "db_url", DBURL) modparam("presence_xml", "force_active", 1) # ----- presence_dialoginfo params ----- modparam("presence_dialoginfo", "force_dummy_dialog", 1) #!endif ``` #### Debugging Data <!-- If you got a core dump, use gdb to extract troubleshooting data - full backtrace, local variables and the list of the code at the issue location. gdb /path/to/kamailio /path/to/corefile bt full info locals list If you are familiar with gdb, feel free to attach more of what you consider to be relevant. --> ``` (paste your debugging data here) ``` #### Log Messages <!-- Check the syslog file and if there are relevant log messages printed by Kamailio, add them next, or attach to issue, or provide a link to download them (e.g., to a pastebin site). --> ``` (paste your log messages here) ``` #### SIP Traffic <!-- If the issue is exposed by processing specific SIP messages, grab them with ngrep or save in a pcap file, then add them next, or attach to issue, or provide a link to download them (e.g., to a pastebin site). --> ``` (paste your sip traffic here) ``` ### Possible Solutions <!-- If you found a solution or workaround for the issue, describe it. Ideally, provide a pull request with a fix. --> ### Additional Information * **Kamailio Version** - output of `kamailio -v` ``` version: kamailio 5.4.3 (x86_64/linux) e19ae3 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_BLACKLIST, HAVE_RESOLV_RES 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: e19ae3 compiled on 18:17:25 Dec 14 2020 with gcc 4.8.5 ``` * **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 `uname -a`) --> ``` CentOS 7 - Linux hostname 3.10.0-1160.2.2.el7.x86_64 #1 SMP Tue Oct 20 16:53:08 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux ``` -- You are receiving this because you are subscribed to this thread.
