debian jail, setting max open files soft limit does not work

Hi all,


I’ve set up a jail on 13.1 running debian stretch, and now a 
triplestore needing many openfiles for a data import.

Since on Linux the soft limit is pretty hard :) I need to set the 
soft limit.

I’ve edited /etc/security/limits.conf to set soft and hard limit 
to 20000 (just to check), but after login the soft limit stays at 
1024.

Using prlimit I can change the limits of a running process, but 
that is not passed on to subprocesses, which the app creates 
constantly for import, there, the soft limit returns to 1024 :(

Running prlimit --nofile 20000 or prlimit --nofile 20000:20000 
does not work, either, the soft limit stays at 1024, and the 
import fails.

Does anyone know a way to change the soft limit permenantly?


Thanks, Mathias
