Etienne Lessard commented on ASTERISK-26078:
--------------------------------------------

I also had a valgrind output from a previous run, so I'll also attach it even though I'm not sure if it helps (that said, we do see something related to logger.c and stringfields.c, e.g.):

{code}
==11069== 1,409,504 (626,672 direct, 782,832 indirect) bytes in 39,167 blocks are definitely lost in loss record 9,148 of 9,151

My tests were done on Asterisk 13.9.1.

> There seems to be a new memory leak since Asterisk 13.8 or 13.9.
> Running a simple call center scenario with sipp (a new call into a queue every few seconds, that is answered by a queue member, etc), I'm seeing asterisk memory usage grow noticeably (a little bit less than 100 MB/hour).
> Looking at a diff from two "memory show summary" commands taken 30 minutes apart, it looks like the leak comes from logger.c / stringfields.c. I've attached the output of two "memory show summary".
> I've also attached the mmlog file, but I doubt this will be useful since it's mostly empty (guess I've done something wrong).
> I'm already aware of ASTERISK-25262, but this is not it: I've explicitly disabled the CEL in my current tests. I've also seen ASTERISK-25905, but this is not it (I've also try manually running malloc_trim, it gave nothing). Maybe it's similar to ASTERISK-26020, but there's not much info in that ticket.
> Thank you
