[wt4hq] RX Buffer Overflow

[Dieter Kritzer]

Dear Larry,
thank you for your reply.

The overflow happens when the size of the already allocated RX Buffer and
the 
size of the new received data exceed 10000 characters.

I guess this happens when a lot of stations send lots of QSOs within short 
time. I found the error in the logfile of the Windows server, but not yet on

the Linux server. Maybe my Linux server is faster in transmitting the data
to 
the other stations and deallocating memory, don't know yet. We'll be testing

the tunnel during the next two days.

Unfortunately my C knowledge is not good enough to be sure about what would 
happen if I set the RX_BUFFER_SIZE_MAX to 20000. The server the tunnel is 
running on has enough memory, I think. Memory allocation should not be the 
problem. Should I give it a try if it happens on the Linux server too?

Thanks in advance,

I guess you're talking abt the tunnel server ?

 From what I see in the (public) code, the socket is closed, and data is
lost.

Sure you can, but there is maybe another reason why it overflows. Maybe it
could be interesting to find.
