[asterisk-bugs] [JIRA] (ASTERISK-25610) Asterisk crash during "sip reload"

[Richard Mudgett (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-25610?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=228547#comment-228547 ] 

Richard Mudgett commented on ASTERISK-25610:
--------------------------------------------

Both crashes are the result of a reentrancy problem with the global bogus_peer being updated by sip_reload().  The bogus_peer needs to be protected using AO2_GLOBAL_OBJ_STATIC() and the associated accessor/manipulation functions.

> Asterisk crashes sometimes when we issue sip reload.  (As seen from back trace, issue is at main/ccss.c, ast_cc_config_params_destroy's ast_free, which is called by destroy peer, which is called by sip reload.)
> I attached 2 different backtraces from 2 crashes, as I see both crash started with 'sip reload', but crashed for different reasons according back trace.
