[Matt Jordan (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-19754?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=205464#comment-205464 ] 

Matt Jordan commented on ASTERISK-19754:
----------------------------------------

There is a patch on ASTERISK-21389 that should prevent res_timing_pthread from blocking callers. That should resolve this issue.

If you test with that patch and this issue is still a problem, please let a bug marshal know in #asterisk-bugs and we will be happy to reopen this issue. Thanks!
