<div dir="ltr">Hi,
<div><br>
</div>
<div>We currently have OpenSIPS crashes that look to be caused
by synchronization issues between the TM and DIALOG modules.</div>
<div><br>
</div>
<div>We started to get these crashes after setting the following
modparam:</div>
<div><br>
</div>
<div>modparam("tm", "own_timer_proc", 2)</div>
<div><br>
</div>
<div>Note that we don't set the own_timer_proc parameter for the
DIALOG module, therefore it uses the global timer process.</div>
<div><br>
</div>
<div>Do you have an idea what may cause the issue?</div>
