seems a significant delay in socket connection in MQX 4.0.2

I started to use MQX 4.0.2 with CW10.2 on K60 device. I noticed a significant delay on socket connection - either TCP or UDP.


in TFTP_read:

sock = TFTP_WAIT(time_left);


TFTP_read is called after issuing RTCS_load_TFTP_BIN() in my program.

The call above sometimes stops for very long time (time_left is 4999). Then continue with new time_left (10000).

This did not happen on MQX 4.0.0

I wonder what is the root cause. I know there are some HW timer related changes in MQX 4.0.2. Are they tested and worked fine?
