[Vortex] Re-2: Re-9: Connection close problems during "file transfer"

Hello Francis,

You are right with the 90112.

It was silly mistake of me.
My default value for the frame size is 32K (0x8000).
For the test with the logs I wanted to double the value, so I took 0x16000 ?!
This is, of cause wrong- It's 88K.

With a value of 0x10000 (64K) the file transfer works the same way like using 0x8000.
It seem to be a little faster but  the "connection close" also happens sporadically -about each 7th to 9th file transfer) using the VORTEX 1.1.4BLD4333-4333.

To check the next stable release to see, if it fixes my issue, please can you
offer me a binary for windows ?
Or it would be also great to give me a description, how to build it by myself
using your source code (setting of path, environments, scripts, etc.)

Best regards
