Two serviio installations working but error messages

I have installed jre1.8_181 and serviio-1.9.2-linux on slackware x64 linux on an
Intel I5 system and serviio-2.1 on a Raspberry Pi 4B system running the latest raspian.

I have done a 'chown -R serviio:serviio /opt/serviio' and renamed serviio.sh
to usr_serviio.sh and written a wrapper script 'serviio.sh' which starts the original
script after a user change as below.
'chroot --userspec=serviio:serviio --skip-chdir / /opt/serviio/bin/usr_serviio.sh $1 &'

I get a never-ending parade of this error message on both systems

'Could not lock User prefs. Unix error code 2.
Couldn't flush user prefs: java.util.prefs.BackingStoreException: Couldn't get file lock.'

I supect it's a file permissions problem but don't know where to change permissions
or in what way. Can anyone help?
