I don't think this has anything to do with Local channels.

Rather, it looks like a locking inversion between reloading the dialplan from {{pbx_lua}} (and one of the dialplan context locks) and a channel lock. Unfortunately, without a {{core show locks}} it's difficult to find the culprit.

A {{bt full}} might give a bit more information such that the culprit can be found.
