Alex,

WaitingTasksQueueOverflow:

The number of threads waiting to deposit a task in the waiting tasks queue when the queue is full.

WaitingTasksQueueOverflow shows the number of blocked threads waiting to submit a task in the queue of waiting tasks. In this situation there are no free threads to process requests and also the size of the queue of waiting tasks is full, so the threads that need to submit a new task in this queue are blocked until a free slot is available. This monitor shows a problem.

This counter is unlikely to change its value from 0 because it means that the capacity of the requests queue is exhausted. This is a severe performance problem.

This can also be a symptom for a locking situation (blocking back-end calls or Java level deadlock).
