Redundant PM866 simultaneously shut down when download with warm-restart
We need your help.
There are 3 redundant PM866 in 800xA system 5.1 FP4(5.1.1-1)
For a redundant PM866 node, both CPUs have been shut down after downloading to CPU.
We just downloaded to CPU in order to allocate a I/O variable by activating a channel on I/O module setting.
I have found some log in CPU log files as below.
Do you have experience with similar problem?
I'd like to know workaround.
