Why I get "#CME ERROR: 36872 " when I use IP connectivity command to listen?

I use Q2406 to listen as a sever. It listens(#LTCPSTART) and stops listen(#LTCPSTOP) once 10 mintutes.

It works well about during 2 hours, but the ERROR "#CME ERROR: 36872 " is given after, and it cannot work well when a client wants to connect it.

I donnot know why this is happened and how to resolve this problem.

Can sb. help me?

Thanks.
