Chapter 2: Common Problem Areas

Server disappears

If the server runs for a while, then disappears:

Check log files for errors. See “Logging” for details.
On UNIX, check to see if a core file was generated. On Windows, check for a .log or .dbg file.
Check the jagsrv console for errors.
If there are no errors, restart the server to capture information next time.
- Start the server from the command line, and redirect the output:
  
  UNIX:
```
serverstart.sh > err.out 2>&1
```
  Windows:
```
serverstart.bat >info.out 2 >err.out 
```
- On Windows, set the crash handler to userdmp.exe instead of Dr. Watson. See Chapter 6, “Advanced Topics,” for more on debugging tools.
- Try the debug server.
Implement a service component to periodically write information to the server log.
