<p><tt>Hi solarmon,</tt></p>
<p><tt>Please find an elaborate discussion on this topic here [1].
In short,<br>
MySQL's "wait_timeout" setting directly affects the number of
such errors<br>
you are seeing in the logs, unless you are dealing with some
other kind of<br>
a DB problem which causes new connections to be immediately
dropped<br>
(e.g. deadlock, internal error, read-only state, etc.).</tt></p>
<p><tt>Best regards,<br>
</tt></p>

<div>As per my last post on this subject, the database it is
using is local to opensips - i.e. running on the same machine
opensips. Thus, there should be no networking or routing or
firewall that could be causing connectivity issues.</div>
<div><br>
</div>
<div>Why is opensips generating such logs suggesting that it
cannot connect to its local database? What could be causing
this issue - opensips or the (MariaDB) database?</div>
<div><br>
</div>
<div>Thank you. </div>

<div dir="ltr">Hi,<br>

</div>
<div>Looking at the logs, these
<a class="moz-txt-link-rfc2396E" href="INFO:db_mysql:switch_state_to_disconnected">"INFO:db_mysql:switch_state_to_disconnected"</a> events do
occur quite regularly.</div>
<div><br>
</div>
<div>Also note that the database is local to the opensips
node (part of a two node cluster, with mariadb
master/master syncing)).</div>
<div><br>
</div>
<div>As per another post (that has not has a response) I'm
using the
"opensipsctl dispatcher show" to monitor the endpoint
status. I think this is related as I've notice that the
state shown by "
"opensipsctl dispatcher show"" and
"opensipsctl dispatcher dump" differ:</div>
<div><br>
</div>
<div>When using "opensipsctl dispatcher show":<br>
<br>
+----+-------+------------------------+-----------------------+-------+--------+----------+-------+--------------+<br>
| id | setid | destination | socket
| state | weight | priority | attrs | description
|<br>
+----+-------+------------------------+-----------------------+-------+--------+----------+-------+--------------+<br>
| 1 | 1 | sip:A.B.C.D:5060 | udp:W.X.Y.Z:5060 |
2 | 1 | 0 | | |<br>
<br>
When using "opensipsctl dispatcher dump":<br>
<br>
SET:: 1<br>
URI:: sip:A.B.C.D:5060 state=Active
first_hit_counter=0<br>
socket:: udp:W.X.Y.Z:5060<br>
</div>
</div>
<div><br>
</div>
<div>I might change my monitoring script to use
"opensipsctl dispatcher dump", but it was easier for me to
process the tabular format as it contains the destination
and state in the same line.</div>
<div><br>
</div>
<div>Thanks.</div>

as the level indicates, there are some INFO <br>

The reason for switching the endpoint in probing mode

script to <br>
understand this problem, or take a look at the signaling
