What steps will reproduce the problem?
1. We are using LibreOffice 3.4 on Windows
2. SigarProcessManage is used as process manager
3. ProcessPoolOfficemanage is used as office manager.
4. Currently only one socket connection with port 2002 is running.
5. The execution of a custom conversion task works, and completes successfully
6. We call officemanager.stop() at the end of the process
7. It throws the info message as 
      INFO: disconnected: 'socket,host=127.0.0.1,port=2002,tcpNoDelay=1'
8. I can still see that soffice.bin is running from task manager ( or tasklist 
command)
9. It hangs for about 2.5 minutes.
10 Then throws the following error.

What am I doing wrong. Should I issue another kill command to stop the 
soffice.bin ?
What is the expected output? What do you see instead?


What version of the product are you using? On what operating system?


Please provide any additional information below.

I have figured out how to avoid this, though not quiet sure if the best way to 
do.

ProcessManager processManager = new SigarProcessManager();
Sigar sigar = new Sigar();
long servicePid = processManager.findPid(new ProcessQuery("soffice.bin", ""));
//System.out.println(" Process id = " + servicePid);
// 9 = SIGTERM signal
sigar.kill(servicePid, 9);

This stops the soffice.bin.
