aragon commented on ASTERISK-20335:
-----------------------------------

I went through all of the Asterisk 1.8.16rc1 and svn change logs and recent changes were made to cel.
Therefore I wonder if this is a regression...

	* main/cel.c: Resolve severe memory leak in CEL logging modules. A
	  customer reported a significant memory leak using Asterisk 1.8.
	  They have tracked it down to
	  ast_cel_fabricate_channel_from_event() in main/cel.c, which is
	  called by both in-tree CEL logging modules (cel_custom.c and
	  cel_sqlite3_custom.c) for each and every CEL event that they log.
	  The cause was an incorrect assumption about how data attached to
	  an ast_channel would be handled when the channel is destroyed;
	  the data is now stored in a datastore attached to the channel,
	  which is destroyed along with the channel at the proper time.

> On a pretty busy system we get deadlocks and crashes daily since installing Asterisk 1.8.16rc1
> Upgraded from 1.8.12 because we were having problems with leaking bye's fixed in ASTERISK-19455
> We were able to collect verbose CLI, core show channels, sip show channels, and Asterisk CLI with sip set debug on.
> Also back traced a core dump file but this is an optimized build since we could not run non-optimized in this environment.
> Including the back trace anyway since it might help diagnose the problem.
