In general please note that memory parity errors are h/w state changes(bit flips due to thermal, environment, radiation ) etc. If the error is seen rarely, a device reboot / power drain can help.
request system reboot at now
If the issue persists post reboot then it is likely a hardware failure. Please contact JTAC to create RMA.
