Re: jt400.jar in use

[Jim Oberholtzer <midrangel@xxxxxxxxxxxxxxxxx>]

I agree with Dan.  Exclude it from your save since it is easily 
recovered in other ways, and does not change very often.  Your 
monthly/Quarterly full system saves should be plenty.  (or after a 
group/cumulative installation)

This was at 4:19am with no users signed on.  Controlling subsystem would have been started about 1 hour earlier, and subsystem QHTTPSVR would have been ended when the error occurred.
