RTCS send() fails with error code 0x1639 (RTCSERR_TCP_CONN_RLSD)

GaneshOkade — Thu, 08 Apr 2010 22:49:35 GMT

Dear Experts,

In one of my applications, a called to send() is failing with error code 0x1639. When I look up this error code in rtcs.h I find it to be RTCSERR_TCP_CONN_RLSD with a short description that reads "Connection/TCB released".

- What does this error mean?

- What are the potential causes of this error?

- What should I look for to figure out the root cause?

Thanks.

Regards,

Ganesh Okade

I get the same thing on a recv() at times even though the other party has not issued a graceful shut down. I test recv() again to be sure I don’t close a connection that is not being requested to close. I’m not sure if this is a bug or not.

MQX ver 3.4

Any resolve on your issue?

Hello Mark,

I get exactly the same error when using recv().

Did you find out what was the cause for this issue?

Thanks,

Lior.

Hi Ganesh,

It is possible that you lost conexion and this caused the issue. What is your application doing? What other things is the system doing when the error happens? What MQX version have you tested? Did you tried with MQX 3.8.1 to see if anything changes?

Best regards,

Hello all,

I know this is an old thread, but I had the same problem, upgrading to MQX 4.0.2 and patching it solved this.
