SEL fullness error, I get 5 "n/a" events a minute

I know it may not be a big deal but I want to get rid of this error. IOn one host in vCenter I get the SEL Fullness error and it throws a hardware

host status RED error. I have cleared the log numerous times but I would like to track down the cause of the n/a events. Out of 4 hosts on this vCenter

this is the only one that throws this error.

What else can I check?

TIA
