Hi,
There is a way and I will very much appreciate if you can capture the output. You have to run fop2 on the command line enabling debug, capturing the output. The best way, in my opinion is to:
Stop fop2 as a service
service fop2 stop
And then use gnu screen and script to start fop2_server:
screen
script output.log
./fop2_server -X 15
Then you have to dettach the screen console with ctrl-D
Verify that fop2_server is running:
pgrep fop2_server
You can see the debug output while it is being wrote to disk:
tail -f /usr/local/fop2/output.log
I have fixed some of this crashes already, maybe updating your setup (just replacing fop2_server) will cure the problem, but it would be nice anyways to capture the error as described above. Once fop2_server dies, you can reattach the screen:
screen -r
You will see the last lines and error on your screen. Type "exit" to quit scripts from capturing to output.log, Type "exit" again to quit screen.
