--trace-ascii is following below.

Unfortunately we cant try against another server because we need to talk to that specific kind sever(webservice).
I tried several times, and the resulting trace file is always 110kb big, no matter how long I keep curl running.

The commandline:
D:\>curl -k -XPUT -uAdministrator:xxx -T"D:\3gb_sized_file.dmp"
"https://xxx.16.1.29:8333/folder/testrechner/Thefile.dmp?dcPath=ha-datacenter
&dsName=standard" -g --trace-ascii test4.txt -#

The upload targets a webservice, and as said before works fine with files up to 2gb.

I'll cut out a part in the middle, this is the result:
Do you have
