Problem: The system crashed and left a lockfile

If this is the problem, you might see the error message from the previous section, or you might see rmonitor fail on startup with a comment such as:

error: failed to get shared memory

This means that the rotsed system is not running, but the lockfile is present, perhaps from a previous system failure. The solution is simple: remove the lockfile with:

$ rm /rotse/run/cfg/rotsed.cfg

Then, you can safely restart the system.
