Hi Dennis,
Thanks for your helpful report. I guess it's not yet perfectly clear
whether using the hamlib4.dll from v2.5.4 helped, or whether you were
just lucky for the last 7 hours of the contest.
In any event, it seems that there must be some kind of negotiation issue
between N1MM+ and WSJT-X. Somehow we need to isolate this problem and
see what can be done to make the negotiation more forgiving of delays,
or whatever, and not simply shut down the channel.

I started the contest using 2.6.0RC4. I operate with WSJT in
conjunction with N1MM+, using the DX Lab Suite Commander to a K30/Mini,
through a Remote Rig
unit to the remote transmitting site. I used SO1V mode for this
contest- no SO2R. The combination worked perfectly for about 6 hours,
then the WSJT-X for EW1 just "disappeared" with the TCP error from
N1MM+. I opened Task Manager, killed the orphan JT process, and was
back on the air- for maybe 15 minutes, when it happened again. This
time I Restarted the computer, started up again, and within 30 minutes
it happened again.
Remembering a conversation i had with Joe K1jt a while ago, I then
substituted the 2.5.4 hamlib4.dll for the 2.6.0 dll, restarted the
computer, and started operating again. It lasted about 30 minutes, and
the same error again. I deleted the orphan JT9 process and started up
again. That was the end of the errors- it never happened again for the
next 7 hours of operation.
In his write-up on 3830, Ty, K3MM, also tried 2.6.0rc4 to start the
contest. Within an hour of the start, he had his WSJT-X EW2 window just
disappear. Rather than fight it, he went back to 2.5.4 and had no more
"disappearances" the rest of the contest (about 27 hours).
I typically use 100w or less in contests, but did use 800-1000w for this
contest. I saw no difference in "disappearances" between the two power
categories.
Thanks to all for their work in supporting WSJT-X. Its truly a great
program!
