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

[Ralf Konusch]

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

Ralf
