Dear developers,

Since last Galaxy upgrade some issue with uwsgi and threading arise.
I used Galaxy 
documentation<https://docs.galaxyproject.org/en/master/admin/scaling.html> as a 
guideline to configure galaxy.yml:

uwsgi:

  socket: 127.0.0.1:4001

  http: 0.0.0.0:8080

  buffer-size: 16384

  processes: 4

  threads: 8

  offload-threads: 2

  static-map: /static/style=static/style/blue

  static-map: /static=static

  master: true

  virtualenv: .venv

  pythonpath: lib

  module: galaxy.webapps.galaxy.buildapp:uwsgi_app()

  thunder-lock: true

  die-on-term: true

  hook-master-start: unix_signal:2 gracefully_kill_them_all

  hook-master-start: unix_signal:15 gracefully_kill_them_all

  py-call-osafterfork: true

  enable-threads: true

  mule: lib/galaxy/main.py

  mule: lib/galaxy/main.py

  mule: lib/galaxy/main.py

  farm: job-handlers:1,2,3



When I run Galaxy, I got error message - error: can't start new thread

Also if I run some job which require a lot of threads, I always get error 
message - RuntimeError: can't start new thread
I tried to increase number of processes in /etc/security/limits.conf for galaxy 
user but it didn’t help.

What can be solution? Do you have any idea what could be wrong?

Thanks a lot for your support.
Best,
Marija
