Please try to capture some debug output to see what is going on, you need to stop the running server and start it, something like:

service fop2 stop
cd /usr/local/fop2
script output.log
./fop2_server -X 15

(log into fop2, make some calls, verify it does not show status)

ctrl-C
exit
service fop2 start

at that point you have the output.log to inspect, look for some kind of error or similar... as the log might be quite large, there is no need to post it completely on the forum, you can email it to me or just try to see if there is some evident issue and paste the relevant parts here..

Best regards,
