[asterisk-bugs] [JIRA] (ASTERISK-21162) Deadlock in cdr.c: cdr_batch_lock vs cdr_pending_lock

[Matt Jordan (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-21162?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=204573#comment-204573 ] 

Matt Jordan commented on ASTERISK-21162:
----------------------------------------

I went ahead and committed this in r383839 in Asterisk 1.8. I was able to reproduce the problem and, with the patch, the problem no longer occurs. Testing included using batches of 30 CDRs, triggered both by time delay as well as by accumulation of CDRs.

If you can test this as well to make sure this is resolved that'd be appreciated. If it isn't, just leave a comment here or contact a bug marshal in #asterisk-bugs (or e-mail me!) and I'll reopen this issue.
