Hi,
Check what default init service  yajsw uses. Most modern Linux  (
ubuntu, fedora etc ) flavors use
systemd nowadays.  Secondly check the systemd service name yajsw will use.
... so  if we can assume the service is started with systemd then when I use
util:log-system-out( $msg )
then the systemd  journal log will capture the service log output.
examples:
last 8 entries
journalctl -u eXist.service -o cat  -n 8
follow the log
journalctl -f -u eXist.service -o cat

Bear in mind, I don't use the yajsw wrapper.
It might be doing other magic.
