Hello,
Again this morning. It looks to be during the beginning of the peak. I don't have any
idea where to search the issue. Any ideas?
Regards,
Igor.

Same issue this morning.

So, even the async process has failed.
Could it be an issue on MySQL himself?

Igor.

Hello,
Thank you Daniel, and Daniel :) for your advises and analyse of this problem.
I will also check if the DB replies before the timeout in db_mysql module.
Regards,
Igor.

Hello,
as I said, if the execution if the query takes too long, then async mode doesn't
really solve the problem completely -- the record will not be stored in db because the
client library will cancel the query due to execution timeout. However, the async mode
ensures that the sip traffic is routed, so at least you solve the sip signaling problems.
A complete solution is async mode for accounting together and fixing the database to do
the queries under the timeout value you set to db_mysql module.
Cheers,
Daniel

Hello,
Indeed, I think there are some DB access external of kamailio.cfg.
If accounting process is implied in the freeze of SIP handling, and if aysnc accounting
can solve this, it's my priority. Even if accounting fails due to the timeout you
reminded.
Regards,
Igor.

Hello,
it doesn't have to be from kamailio.cfg, but any query from external tools, like cron
jobs, billing applications, etc ...
Can you measure how long it takes to do a query from the command line? Just try to select
the records by a call-id.
Also, there are some core parameters that will print log messages in case of slow
queries/actions, see the core cookbook.
Moreover, the db_mysql module has some parameters to tune the timeouts.
Cheers,
Daniel

Hello,
There is only queries on a replication server, so not the one reported in the errors, to
make some fraud detections. But, directly from Kamailio config file, there's no
queries.
The structure is: id as primary and callid is an index.

Igor.

Hello,
it is a lot if you have over 9 million records. Do you run other periodical queries over
acc, like generating full cdrs every N minutes?
Have you created other constraints (e.g., unique keys) over the table?
Cheers,
Daniel

Hello,
do you have a lot of records inside the acc table?

Hello,
Two times in the last week, Kamailio reports MySQL errors like these:
/usr/local/sbin/kamailio[19225]: ERROR: db_mysql [km_dbase.c:126]:
db_mysql_submit_query(): driver error on query: Can't connect to MySQL server on
'192.168.2.6' (4) (2003)
/usr/local/sbin/kamailio[19225]: ERROR: <core> [db_query.c:235]: db_do_insert_cmd():
error while submitting query
/usr/local/sbin/kamailio[19225]: ERROR: acc [acc.c:504]: acc_db_request(): failed to
insert into database
These errors are repeated many times and cause Kamailio to hang and don't reply to SIP
requests. A reboot of Kamailio solves the issue.
Anyone has already had this issue and had solved it?
Regards,
Igor.
