Artem, can you recompile Asterisk with the BETTER_BACKTRACES compiler flag in addition to DEBUG_THREADS and then get the "core show locks" output again?

You can see an example of how it is helpful, [here on the wiki|https://wiki.asterisk.org/wiki/display/AST/CLI+commands+useful+for+debugging#CLIcommandsusefulfordebugging-coreshowlocks].
