Still you didn;t answer to my question on the CRITICAL error -
according to the backtrace, you should have a CRITICAL message
in the opensips log, just before the crash.<br>
<br>
In GDB, do:<br>
f 2<br>

<div>Hello, Bogdan!</div>
<div> </div>
<div>No, i cannot see in the log any messages
you mentioned it your letter.</div>
<div>The situation dealing with crash had such
stage.</div>
<div> </div>
<div>1. I prepared to migrate to 2.2.3 from
2.2.2. But do not have a time to restart
Opensips</div>
<div>2. As a result "i waited" when Opensips
have crashed. During crash of 2.2.2 no core
file has been generated, but Opensips has been
restarted using cron.</div>
<div>3. After 2) Opensips became 2.2.3. It was
working about 1 minute and crashed again, but
in that time, core file has been generated and
i attached information from it.</div>
<div>So, between 2) and 3) , as i mentioned
above, there were no messages about memory,
but i see many messages like</div>
<div>'WARNING:core:utimer_ticker: utimer task
<tm-utimer> already scheduled for 71500
ms</div>
<div>WARNING:core:timer_ticker: timer task

<div>and so on</div>

<div bgcolor="#FFFFFF">Hello Denis,<br>
<br>
Thank you for the report. Do you see any
CRITICAL log just before the crash,
something like:<br>
"bad pointer 0xxxxxxxx (out of memory
block!) - aborting"<br>
?<br>
If yes, please post here the exact line.<br>
<br>
Also, do you use the latest OpenSIPS 2.2
from GIT repo ? (run "opensips -v")<br>
