This is a known issue when the users are Online monitoring or forcing I/O located within 32-bit modules over a Ethernet connection; there is no firmware mitigation.
The only suggested recommendation is the use of DH+ user software communications when performing the above mentioned tasks.

I was doing some research and looks like this error is related to was a “BACKGROUND ROM check that failed after power up”, they recommend is to have the controller repaired.
