So when I try to start asterisk via systemd I get:<br>

If I then connect to the console asterisk is running fine, in this case Asterisk restarts randomly (every 1-2 minutes). If I then start asterisk myself by doing:</div><div>

<br></div><div><br></div><div>Then it starts fine and works with no issue. It would seem there is something with systemd that is causing Asterisk to restart. I don't think it's the actual script since I would then expect it to always restart at the same time though I am not able to find any dumps any where on the box.</div><div><br></div><div>Any ideas?</div></div></div></div></blockquote><div><br></div><div>Look in /var/lib/asterisk. <font size="2">That's the home directory that the service file sets.

The default version from apt is 13.18.3 so you may have a mixed installation that's causing issues.</div><div><br></div><div>Run "dmesg" after asterisk dies. If it actually crashed, there'll be a message in the kernel log.</div><div><br></div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div class="gmail_extra"><div class="gmail_quote"><div><br></div><div><br></div></div></div></div>
