Can not send SMS when more than 11 SMS in queue

Confirmed its a bug. I know what happened, and currently being fixed.

sendsmsd_queue value in config.php limiting the number of queue that can be processed at one time. But since your 10 other queues were scheduled for later then the 11th queue and the next will not be processed until the earlier 10 scheduled SMS sent.

See this:

Those queue are sorted latest on the top. The first on the top wont get sent at 20.45 if the other 10 at the bottom processed/sent. It will be sent around 21.00 soon after the other 10 sent.

temporary solution

edit config.php, set sendsmsd_queue to 0 and restart playsmsd
