Here's what happens when restarted on a different host:

[42000] ERROR at sysvipc.cpp:775 in postRestart; REASON='JASSERT(_realId != -1) 
failed'
      (strerror((*__errno_location ()))) = No such file or directory
java (42000): Terminating...

As for the other problems (relative versus absolute path for stderr of a Java
process), either I had confounded it with the above or it does not happen every
time, so I may have been wrong about it, and in any case do not currently have
failure output for it.
