[OpenSIPS-Devel] FIFO Bug / lb_reload

[Alec Fett]

I've figured out the problem is not related to the number of calls, but
actually occurs after using lb_status to change the status of a gateway, and
then later reloading the list with lb_reload. The following occurred after
issuing `lb_status 1 0` and then later trying to lb_reload

Thanks!
