Tips<br>?</div></div></blockquote><div><br></div><div>The wiki[1] has instructions for getting a backtrace for a deadlock from a running process. It can be used to isolate why things are blocked. Generally, though, when realtime is involved I've found that it usually ends up being the database or that interaction in some way. Any hiccup or issue there can result in blocking in Asterisk. </div><div><br></div><div>[1] <a href="https://wiki.asterisk.org/wiki/display/AST/Getting+a+Backtrace#GettingaBacktrace-GettingInformationForADeadlock" target="_blank">https://wiki.asterisk.org/wiki/display/AST/Getting+a+Backtrace#GettingaBacktrace-GettingInformationForADeadlock</a></div></div><div><br></div>-- <br><div dir="ltr"><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div style="font-family:tahoma,sans-serif"><font color="#073763">Joshua C.
