[Sean Bright (JIRA)]

     [ https://issues.asterisk.org/jira/browse/ASTERISK-19767?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Sean Bright closed ASTERISK-19767.
----------------------------------

    Resolution: Cannot Reproduce

A lot of the locking behavior was changed Asterisk 13.14 and 13.15 that most likely addressed this. If you are able to reproduce with 13.15 or newer, please feel free to re-open.
