I've been told I have some page fault errors; the extract from syslog is shown below and diagnostics are attached.

 

I'm running 6.11.5 and, if it's relevant, I have ECC RAM. According to the Event Log that I can get from IPMI there are no relevant errors (the l last recorded error was in 2020.)

 

How can I fix these page fault errors? Or at least narrow down the possible cause?
