When running LM-X on a Linux operating system, you may see an "exit signal" error in the log; for example:
[2012-02-08 15:48:15] WARNING: Unable to establish connection with HAL peer 6200@193.28.180.39. Please make sure the host is up! [2012-02-08 15:52:35] Shutting down due to exit signal 15
Exit signal errors are Linux operating system errors, rather than LM-X errors. You can find information about exit signal errors at http://www.comptechdoc.org/os/linux/programming/linux_pgsignals.html.
