Yes, sorry, I mean exactly what you have done.
Try one time incrementing the sleep time (around line 164) in seahub.sh to 10 and see if you get the Error:Seahub failed to start and Please try to run ./seahub.sh start again or you don’t get any error.
Insert the pdb -m code at the python execution line in seahub.sh script:
$PYTHON -m pdb $gunicorn_exe seahub.wsgi:application -c "${gunicorn_conf}" -b "0.0.0.0:${port}" --preload
then press “n” and compare with my output:
seafile@hiperborea:~/seafile-server-6.2.2$ ./seahub.sh start

wsgiref (0.1.2)try to update pip, but here is not our problem. I checked for requests and urllib3. You have both. Runned out of ideas 
Try with 6.1.2 and with wsgi. WSGI is working for me already in 6.1.2. You can let your nginx config as it is. Tell me if it does work wsgi with 6.1.2.
Have you installed wsgiref?
Looks like wsgiref is installed:
pi@pi31:/mnt/pidrive/seafile $ sudo pip install wsgiref
Requirement already satisfied (use --upgrade to upgrade): wsgiref in /usr/lib/python2.7

Tested the start of seahub again
Error:Seahub failed to start.
Please try to run “./seahub.sh start” again
@lins05 is possible you take a look at this issue? Thanks in advance
While trying to go back to 6.1.1 I´ve finally found the mistake which let the seahub crash.
Here @Jack_Miller suggested to change the BACKEND value to 'BACKEND': 'django_pylibmc.memcached.PyLibMCCache' which I did a week ago.
An hour ago I´ve changed it back to my previous value: 'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache' and everything works fine (in version 6.1.1, 6.1.2 and 6.2.2).
Looks like the answer was there all time time 
Thanks a lot guys for your assistance
Lol, der Teufel steckt im Detail. Minor changes should be evaluated without the influence of major changes.
Hmm, OK. So for MikeMeyers reverting back the “Backend changes” fixed it for him. I seem to have the same issue with Seahub not running although not using any of the memcached stuff
What can I provide you guys to support me on my problem?
Please post more details, or create a new thread with exactly what you have done
I think that their is any issue arise in its supporting software. So it is need to check and update properly or check Os of server and configure again.
