<p class="MsoNormal">If you’re running on an unsupported version, you’ll want to upgrade the version to a supported one first (2.4 or 3.0). If you’re already on one of those, or after upgrading, try running the latest revision (HEAD) of the respective branch
from GitHub. Both of these steps are to make sure the crash has not already been fixed.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">If the crash still occurs, you should check the open GitHub issues [1] to see if anyone has already reported a similar crash. If not, you should open a GitHub issue using the [CRASH] template. There are instructions on the OpenSIPS site
[2] on how to gather the necessary information.<o:p></o:p></p>

<p class="MsoNormal">This is the process I have followed and seen recommended in the past. I do not make any claim that it is the official process.
