N4032 - Swtich parity error

hi,

I got yesterday (once) this error block, firmware version is 6.3.3.10:

The error has not reappeared and everything as far as I can tell is working properly. This is a stack of 2 N4032 switches. The switch nor the stack have not been rebooted. I have seen some parity errors on this forum but not the one I got. Does anybody know what is means or can point me to a some manual where errors would be listed ? I checked N4032 documentation but did not find any reference to parity errors. Maybe there is nothing to do or maybe I just show reboot, or update firmware. I appreciate any input. Thank you
