[asterisk-bugs] [JIRA] (ASTERISK-29698) Segfault if sorcery object_lifetime_maximum and qualify_frequency the same value

[Alexei Gradinari (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-29698?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=256827#comment-256827 ] 

Alexei Gradinari commented on ASTERISK-29698:
---------------------------------------------

I tried to run on test server with refdebug = yes and on startup got another segfault in __ao2_ref

astobj2.c:658
if (ref_log && !(obj->priv_data.options & AO2_ALLOC_OPT_NO_REF_DEBUG)) {

but obj is already freed, look at line 642
ast_free(obj);

Should I create a new issue or you'll do it?

> [res_pjsip]
> endpoint=realtime,ps_endpoints
> endpoint/cache=memory_cache,maximum_objects=3000,expire_on_reload=yes,object_lifetime_maximum=30
> aor=realtime,ps_aors
> aor/cache=memory_cache,maximum_objects=3000,expire_on_reload=yes,object_lifetime_maximum=30
> The endpoint with aor's static contact and qualify_frequency = 30
> I think one thread 'sorcery_memory_cache' clears cache due to expiry
> and another thread 'pjsip_options' uses the same cache object which is already freed.
