I have changed all my local-users password for the type password simple and the issue remains the same.

Same issue here with a stack of 3 5500 units.  Tracked it down to the snmp config, as it can save fine if I turn that feature off and delete all lines, but as soon as I add it back I get the checksum error.  I've manually examined the files too, and all are exactly the same so I'm at a loss here.

Firmware on all three was updated prior to forming the stack, and is V3.03.02s168p23.
