Bug Description
When doing simple copy-jobs with large files (f.ex. Partition Images > 4 GByte filesize)the file transfer allways stall after about 16 GByte has passed to the Client.
No Problems using kernel-versions up to kernel 4.2 (Ubuntu 14.04 up to 15.10).
Verified with new installations of 16.04 LTS as well as upgraded (previous working) 15.10 workstations to 16.04 LTS.
Autonegotiated NFS-values are still the same:
Working 15.10 version:
