Queues getting full?

Hi,

we having some weird issue with FreePBX + FOP2.
The calls are randomly getting stuck with ‘welcome message’ saying you are 1st or 2nd in the queue. But the the queue its empty and no calls are done.
When a call get stuck with a music, number its not visible in any logs.
FreePBX 2.11.0
Full log (from the time, i was trying to reach one of our numbers - with no luck, got stuck in a ‘queue loop’):
