Hello,. Liviu!

I saw in log "too many reconnects". Unfortunately it does not reflected in log files that i attached early but it was there.
I have two servers with two mysql + Opensips  installation. As you probably gassed one server is active and another is stand by. 
Active server has "Server version: 5.5.50-0ubuntu0.12.04.1-log (Ubuntu)" mysql installation and standby  server has "Server version: 5.5.44-0ubuntu0.14.04.1-log (Ubuntu)" mysql installation.
Respectively active server has "Ubuntu 12.04.5 LTS precise" and standby has "Ubuntu 14.04.3 LTS trusty"
Mysql replication master-master has been customized between two servers.

Hi Denis,
Looking through the logs, this one seems to be relevant, and we need to understand the root cause for why it's happening:
Aug 19 17:00:37 opensips-main /usr/local/opensips2.1/sbin/opensips[17749]: WARNING:drouting:dr_load_routing_info: table "ast_dr_rules" is empty

As far as I can understand, one "dr_reload" command finds the table empty, then the next one properly retrieves the data! Although I see several disconnect events in there (for each process!), the driver should have reported "too many reconnects" errors if those were really the cause.

Could you provide more info about your MySQL setup? Is it a server, slave or cluster? What software and what version?

Any ideas about the problem?

Hello, Bogdan

I am sorry that i did not describe the problem more clearly.
404 opensips sends because in opensips.cfg i wrote a logic that if in dr_rules opensips finds no rules for routing it must send 404.
And the problem i think is there. Opensips began rejects all calls with 404, i.e. it could not find any rules in dr_rules table.
Everthing began fine after fifo dr_reload command execution, i.e. after dr_rules updating.

OpenSIPS by itself does not send any 404. If it does, it does it because you put that into the script. So, you have to look into your script and see the logical path that makes OpenSIPS to get to sending a 404 reply.

You may use the script_trace :

Some time ago i wrote about a problem when Opensips began reject all calls with 404 code.
Unfortunately i did not received any answer.
Since that time i have made upgrade from 2.1.2 to 2.2.1 and today i have got the same problem. Opensips began rejects all calls with 404 code. 

Based on the information from log, i make suggest that problem began when dr_reload command has been received. 
And the problem has been solved, again, when the dr_reload command has been received (the period about two commands is about a couple of minutes).

I please help to solve the problem. 

Thank you.

Recently i begun to get such problem.
Opensips rejects all calls with 404 code. I can solve the problem by making dr_reload.
I tried to analyze a log and what i could found you can see in attachment.
As i could understand last problem began after dr_reload.

Thank you for any help.
