Re: TCP/IP starts twice in V7

This actually wound up spawning two problems. First there are a number of PTFs for Telnet. According to the support folks you really need:

Latest Cumulative + SI46687, SI46902, MF55751. SI46687 seems to be the important one.

Second IBM i is clearly starting TCP twice. The IPL attributes are set to start TCP and there is no STRTCP anywhere in any of the start up procedures. The TCP start up is submitted by QSYSARB4. Since there is no real job log on that system job we have not been able to dig much further without IBM.

Is anyone else seeing that?

Hi Jim,

"Client machine keeps crashing the Telnet Server."

This is the issue with V7R1. After upgrading from V5R4 to V7R1, we also
faced the same problem.

I would suggest you to try this.

ENDTCP before ENDSBS *ALL *IMMED

If the Telnet server is not ended prior to the ending of subsystems, it
might not automatically restart. To circumvent this and other potential
problems it is suggested that prior to ENDSBS *ALL *IMMED these steps be
taken:

1. ENDTCPSVR *ALL
2. ENDHOSTSVR *ALL
3. Allow the commands to complete and the servers to end. If issuing the
commands from a CL program include a DLYJOB DLY(300) to allow the commands
to complete.
4. ENDTCP


Also, there are PTF's recommended by IBM.


Thanks
