Issue:

The ATCP thread could become blocked by a time-consuming operation while executing the ePolicy socket function.


Fix Details:

A counter-based mechanism was introduced to trigger the ATCP thread to assist adjacent threads with packet reception. Additionally, a lock was added to protect sections where non-thread-safe data is modified.
Result:

As shown in the partial atcp.log below, atcp2 periodically assists atcp3 in receiving packets (and vice versa).
