Richard Mudgett commented on ASTERISK-28044:
--------------------------------------------

The crash you had in v14 is different than the crash you are having in v15.  IIRC the crash in v14 was fixed in other branches after v14 maintenance support ended.

The v15 crash is in libjansson.  What version of libjansson are you using?

There are fixes in libjansson 2.11 that improve reentrancy issues.  In fact one of the enhancements added in v15.6.0 was to bundle libjansson in a similar manner to pjproject so you could use 2.11.
{noformat}
./configure --with-jansson-bundled --with-pjproject-bundled

> Asterisk is used with a mix of dialplan and ARI applications.
> Under normal conditions, Asterisk crashes randomly and generates backtraces which may change from one time to another. Please find attached one of those backtraces.
> This crash is reproducible systematically under stress conditions.
> The crash stops happening if ast_channel_varset_type events are disabled in stasis.conf.
