[asterisk-bugs] [JIRA] (ASTERISK-28609) Memory Leak in res_rtp_asterisk.c

[Ted G (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-28609?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=249086#comment-249086 ] 

Ted G commented on ASTERISK-28609:
----------------------------------

I thought it should closely match the number of channels but I guess that's not right?

I guess I miss-understood what Corey was getting at when he asked for the same information and asked:

"How many channels were active when you retrieved this information? Please post the complete output of asterisk CLI memory show allocations res_rtp_asterisk.c and tell us how many channels were active at the time of retrieval."

If everyone thinks the patch is the answer, then I'm OK to close the issue out.  If memory goes crazy again I can reopen. Will the patch be in the next version?

> Hello,
>   There appears to be a memory leak in frame.c.
> Sometimes I received these errors in my logs:
> [Nov  5 21:14:49] WARNING[14918][C-00028a27]: file.c:258 ast_writestream: Translated frame write failed
> I believe this happenes because of some issues between my carrier and the asterisk system and most of the time these errors are not frequent.
> However sometimes these errors are produced thousands of times per day and when that happens the memory usage for asterisk shoots up and never recovers:
