HP Proliant DL380G7 crashed with error message: "uncorrectable pci express error"

[SBogomolov]

Good day!

Our server HP Proliant DL380G7 crashed with error message:

"uncorrectable pci express error (embedded device, bus 0, device 0, function 0, error status 0x00000000)"

Server worked for ~300 days before that. Server was restarted and problem still not happened.

I inversigated:

1) https://community.hpe.com/t5/ProLiant-Servers-ML-DL-SL/Proliant-DL380-G7-Fatal-PCI-Express-Device-Error-PCI-B00-D00-F00/td-p/5313433 

In that post problem happened only at boot.

2) https://community.hpe.com/t5/ProLiant-Servers-ML-DL-SL/DL380p-Gen8-with-uncorrectabl-PCI-express-error/td-p/5995669 - 380p G8

In that post different Device and Function. Also server's model is different so recommendation to update system ROM does not fit.

3) https://community.hpe.com/t5/ProLiant-Servers-ML-DL-SL/PCI-Bus-Error-Slot-0-Bus-0-Device-0-Function-0/td-p/4736039

It’s also different model of server.

Please help what to do? How to prevent server from crashing?

Attached iLO log with error.

System firmware version is 22/06/2010.
