[lxc-users] Containers seem to cannot spawn new processes

[Jäkel, Guido]

Dear all,

during some private chat communication with Lukas it turns out, that (at least) the limit for the number of file handles per user (ulimit -n) was much too low for real world usecases . It was set at 1024 for all user, as well on the host as on the containers. I advise him to adjust  nofiles  at  /etc/security/limits.conf  for the containers and choose an appropriate higher value on the host.

@Dev: If there's a caveat section in the man pages, this might be worth to mention. Maybe even  lxc-checkconfig  should display the current limit and might warn about real low values like this.


Greetings

Guido
