Hello,
Thanks a lot for your (super) fast response! Highly appreciated!
These are the outcomes regarding your mail;
> *In your systemd script, I didn't see the following line under
> [Unit]:After=syslog.target network.target*
We have added the line After=syslog.target network.target to tomcat.service
file. Same result (status code 143).
> *Does daemon.sh stop return immediately,or does it not return until the
> Tomcat (jsvc) process is stopped?*
It does return AFTER JSVC stopped. This was observed using two console
windows, one giving command to stop tomcat service and one watching ps for
the JSVC instance (0.1 seconds interval).
We started the daemon.sh ourselves using
/opt/apache-tomcat/apache-tomcat-8.0.24/bin/daemon.sh start (pass)
We stopped the daemon.sh ourselves using
/opt/apache-tomcat/apache-tomcat-8.0.24/bin/daemon.sh stop

Correct. We have tried with sleep 10 now as well. But that does not help
with the problem. We have found out that when we start tomcat using
init.d/tomcat start, there is an OK back to terminal, but tomcat has not
finished deploying webapps (see also 30 seconds ROOT deployment note below)
during server startup. On the next restart (which stops tomcat first),
tomcat has not finished server startup and then returns error 143, because
we stop it before it finished starting.
We have also noticed that startup of webapps/ROOT can take a long time.
See the log below for an example of a startup time > 30 seconds;

Thanks again!
