[SR-Users] mq_fetch and while loops

[Watkins, Bradley]

I'm having an issue trying to use the construct show in the module documentation.

The docs show:
while(mq_fetch("myq"))
{
   xlog("$mqk(myq) - $mqv(myq)\n");
}

And I'm doing essentially the same thing (differently named mqueue, but otherwise identical), but invariably I get this in the logs:
ERROR: <core> [action.c:1388]: ERROR: runaway while (559, 28): more then 100 loops

Am I doing something wrong, or is mq_fetch not returning appropriate values for successful versus failed fetches?
This is on Kamailio 3.1.4, FWIW.

Regards,
- Brad
