The process starts as a service, so it does not require a shell:
-----------------------------------------------------------------------
root@conference:~# systemctl status jitsi-videobridge
● jitsi-videobridge.service - LSB: Jitsi Videobridge
Loaded: loaded (/etc/init.d/jitsi-videobridge)
Active: active (running) since Tue 2017-02-07 08:25:10 ART; 24h ago
Process: 410 ExecStart=/etc/init.d/jitsi-videobridge start
(code=exited, status=0/SUCCESS)
CGroup: /system.slice/jitsi-videobridge.service
└─434 java -Xmx3072m -XX:+HeapDumpOnOutOfMemoryError
-XX:HeapDumpPath=/tmp
-Djava.library.path=/usr/share/jitsi-videobridge/lib/native/linux-64 -...

-----------------------------------------------------------------------
I had thought that I could add something to the script that starts the
process, but I'm not sure if it's the best idea from the point of view
of maintainability because a package update could eliminate that change.
Another alternative might be to add something like this to /etc/rc.local:
-----------------------------------------------------------------------
PID_JVB=`ps -u jvb | tail -1 | awk '{ print $1 }'`
prlimit --pid $PID_JVB --nofile=10240:10240
-----------------------------------------------------------------------
But perhaps there is another more elegant way to achieve this.
Thanks for your reply.
Kind regards,
Daniel
