@epriestley Thank you very much for this fix and the explanation!
It seems that this issue is now finally solved and can be closed.
Great start of a new year! ;)

Today I`ve had some more time and investigated this issue a bit further.
I tried to debug this issue by using gdb and figured out that after a while the method DiffusionGitSSHWorkflow->waitForGitClient() in DiffusionGitUploadPackSSHWorkflow.php:35 loops forever:

[0x7f595b9d4208] stream_select(array(1)[0x3efe808], array(0)[0x3efe718], array(1)[0x40fb4c8], 1, 0) /home/build/phabricator/libphutil/src/channel/PhutilChannel.php:197

Same here... Sadly D14801 doesn't fix this issue.

As a temporary workaround our company currently uses direct checkout through the standard ssh server until we have a stable phabricator-ssh daemon available.
I hope this will be fixed soon...
Thanks anyway!

Again I attached strace to narrow down the problem further.

Same as @cole... I've reported this issue with an already up to date OS and GIT:

After playing around a while I found out that it seems the hang occurs only if another user concurrently does a git clone:

Yes, the path to 'repo.git' looks like this: plink.exe git@<our_server> "git-upload-pack '/diffusion/TPTB/3RDPARTY/tbb.git'".
I've tried running sshd in debug mode, but the sshd is terminating on every new connection attempt, because it isn't running as a daemon.
The only logging output I got when my clone attempt gets stuck is the following on the server side:
