USRLOC module - Not all records are written to the db with db_mode 2
by Markus Bönke 15 Nov '22

15 Nov '22

Hello NG, we are using Kamailio 5.4.2 with the USRLOC module configured with db_mode 2 (Write-Back scheme). The database is Postgres 11. Sometimes some records are not written to the database, however I can lookup them by "kamcmd ul.lookup ..." . There are no database errors (like constraint violations or value too large errors) to see in the postgres.log. Not even when I execute "kamcmd ul.flush" manually. There are also no related error messages to see in the Kamailio.log during "kamcmd ul.flush". Has anyone else seen that issue or is this might already fixed in a newer version? Thanks and regards Markus

set_dlg_profile profile name with and without value?
by Benoit Panizzon 15 Nov '22

15 Nov '22

Hi I am wondering, if a profile with value can on the same time be used as profile without value of this usages exclude each other. Like doing: set_dlg_profile("caller"); set_dlg_profile("caller","$si"); get_profile_size("caller","$var(c_total)"); get_profile_size("caller","$si","$var(c_ip)"); xlog("L_INFO", "$cfg(route): Total Caller: $var(c_total)\n"); xlog("L_INFO", "$cfg(route): Caller from $si: $var(c_ip)\n"); I fear this is not possible, as I keep getting: w_set_dlg_profile_helper(): invalid value parameter and w_get_profile_size_helper(): invalid value parameter right?

Tcp/websocket closing
by David Villasmil 14 Nov '22

14 Nov '22

Hello all, Question: Say there’s a client connecting via websocket, makes a call and then unregisters. But kamailio sends a 401 expecting the client to authenticate. If the client doesn’t, and simply stays there, at what point is the socket closed? Is it the OS timeout? Thanks! David -- Regards, David Villasmil email: david.villasmil.work(a)gmail.com phone: +34669448337

Uneven-distribution of calls
by satyaprakash ch 14 Nov '22

14 Nov '22

Hi, what would be the reason for the *Un-even* distribution of calls from kamailio proxy to freeswitches. The dispatcher lists are having the same weight. For example: If we are having 4 freeswitches, the calls are evenly distributing for 3 freeswitches but there is high calls for the 4th freeswitch. The dispatcher weight for the freeswitches are: rweight=50;weight=50;cc=1; Thanks and regards, Satya

kamcmd dlg.list => ERROR: reply too big
by Benoît Panizzon 14 Nov '22

14 Nov '22

Hi List I fear I am loosing dialogues somehow. We have implemented counting concurrent connections from customers by using set_dlg_profile. Sometimes, the concurrent channel count does not decrease, despite the dialog end being detected. Now I suppose I have maybe a dozen concurrent calls running, but kamcmd dlg.list is unable to dump the list. kamcmd dlg.dump_file generates quite a large file. I was running into SHM issues while load-testing and had to increase SHM to 1024 to accommodate all dialogues and vars. I fear this could have caused corrupted dialogues? Dialog Data is replicated via DMQ between two instances which I too care never to restart at the same time. Will completely stop and then restart the two affected instances and clear the dialog and dialog_vars tables to see if this issue is manifesting itself again. -- Mit freundlichen Grüssen -Benoît Panizzon- @ HomeOffice und normal erreichbar -- I m p r o W a r e A G - Leiter Commerce Kunden ______________________________________________________ Zurlindenstrasse 29 Tel +41 61 826 93 00 CH-4133 Pratteln Fax +41 61 826 93 01 Schweiz Web http://www.imp.ch ______________________________________________________

External script
by Володимир Іванець 11 Nov '22

11 Nov '22

Hello! I was wondering how everyone uses exec_cmd(). I'm using it to call an external script directly from a worker route which locks it for the time of execution. If all that is needed is to call it and forget, should the best option be to call the async route with exec_cmd()? Thanks a lot for any input on this topic!

Kill child process created by app_python module
by Marat Gareev 11 Nov '22

11 Nov '22

Hello! I'm trying to use app_python module to perform periodic actions. This is a simple python code def _update(): while True: _action() time.sleep(60) class noop_handler: def child_init(self, rank): return 0 def ksr_request_route(self, msg): return 1 def mod_init(): # signal.signal(signal.SIGTERM, signal.default_int_handler) proc = multiprocessing.Process(target=_update) # proc.daemon = True proc.start() ksr.notice('Forked process {} to update\n'.format(proc.pid)) return noop_handler() After killing kamailio processes with SIGTERM signal (killall kamailio) I see zombie process. And if I try to process the signal in daemon mode (see the comments in the snippet above), I get critical errors in the logs and still see processes: 0(37001) NOTICE: <core> [core/kemi.c:124]: sr_kemi_core_notice(): Forked process 37002 to update 1(37003) ERROR: <core> [core/udp_server.c:464]: udp_rcv_loop(): recvfrom:[4] Interrupted system call Process Process-1: Traceback (most recent call last): File "/usr/lib64/python2.7/multiprocessing/process.py", line 258, in _bootstrap self.run() File "/usr/lib64/python2.7/multiprocessing/process.py", line 114, in run self._target(*self._args, **self._kwargs) File "/tmp/script.py", line 155, in _update time.sleep(period) KeyboardInterrupt 0(37001) ALERT: <core> [main.c:774]: handle_sigs(): child process 37002 exited normally, status=1 0(37001) INFO: <core> [main.c:802]: handle_sigs(): terminating due to SIGCHLD 1(37003) ERROR: <core> [core/udp_server.c:464]: udp_rcv_loop(): recvfrom:[4] Interrupted system call 8(37014) CRITICAL: <core> [core/pass_fd.c:277]: receive_fd(): EOF on 4 1(37003) ERROR: <core> [core/udp_server.c:464]: udp_rcv_loop(): recvfrom:[4] Interrupted system call So, how I can kill child process by SIGTERM signal?

acc module => account register messages?
by Benoît Panizzon 11 Nov '22

11 Nov '22

Hi Is there a way to get register messages into accounting? This could come in handy while helping figure out if clients were not registered while calls attemted to reach them. -- Mit freundlichen Grüssen -Benoît Panizzon- @ HomeOffice und normal erreichbar -- I m p r o W a r e A G - Leiter Commerce Kunden ______________________________________________________ Zurlindenstrasse 29 Tel +41 61 826 93 00 CH-4133 Pratteln Fax +41 61 826 93 01 Schweiz Web http://www.imp.ch ______________________________________________________

Hi Team, I want to know this reason - why kamailio only can connect to mysql using */tmp/mysql.sock <https://phonecom.atlassian.net/browse/VOIP-1760?atlOrigin=eyJpIjoiNzY1NjU4Y…>* and why it can’t use /run/mysql/mysql.sock Thanks and regards, Satya.
