I reported this back in October:

    http://lists.sip-router.org/pipermail/sr-users/2010-October/065740.html

A fix was committed to the master branch almost immediately:

    http://lists.sip-router.org/pipermail/sr-dev/2010-October/009499.html

I requested that it be backported into the 3.1 branch in May and it was 
done:

    http://lists.sip-router.org/pipermail/sr-dev/2011-May/011132.html

However, I don't know that it's made it into the tarballs yet.  You can 
get the 3.1 branch with the fix by doing this:

    git clone git://git.sip-router.org/sip-router -b 3.1

Otherwise, here's the workaround I was using before:

       while(mq_fetch("myq")) {
          ...

          if(!defined $mqk(myq))
             break;

           ...
        }

Cheers,
