Two possibilities for this one:
1) User has pressed 'Exit Now' button on dialogue that pops up when neverfail is exiting. This error will *always* be displayed when user does this, and user gets warning NOT to press the 'exit now' button, but to wait.
2) While neverfail is exiting (whether exit was initiated by java or native code), the java code will set a flag to say 'I am still busy doing my exit' The native code checks for this, if it does not see it (it occurs every 30 secs) then the native code will force an exit of the nfserverr2.exe process and this error will be logged. Again, there maybe times when the controller is not doing the right thing - a refactor of controller code is whats required here at some stage.
