             Summary: __ao2_ref_debug() logs to /tmp/refs when REF_DEBUG is not defined
                 Key: ASTERISK-21785
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-21785
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Resources/res_xmpp
    Affects Versions: 11.3.0
         Environment: Embedded Linux - AstLinux 1.x
            Reporter: abelbeck


When __ao2_ref_debug() is called, very often when res_xmpp is actively used, the /tmp/refs file grows to 9MB over the course of a few weeks.

In our embedded environment /tmp is RAM based and defaults to 10MB, the growing /tmp/refs file then causes problems.  We need a way to control this behavior.

A fix is to only log to /tmp/refs in __ao2_ref_debug() when REF_DEBUG is defined.  Possibly this is too simplistic of a test in general, but works for us.  Patch to follow.
