Problems with HA (again)...the HA ports seems to go down randomly

Can you log to both appliances via SSH and check the dmesg for this Interface. 

dmesg | grep Port7 | less

hi LuCar, take a look on the images below....this is the auxiliary....

Hello Tyler,

Thank you for contacting the Sophos Community!

Please open a case with support and provide me the Case ID.

Most likely you might be affected by NC-64907, there should be a patch available.

To confirm if you are affected by this please, gather some console logging from the Aux device.

Note: Be sure that the computer in question does not go into Standby or Hibernate while logging.

Using PuTTY, go to 'Session' - 'Logging.'
Here, select "All session output', and set the file name to a folder and name for later retrieval.
Configure the Serial connection to use the proper COM port on your PC and a Speed of 38400.
Start the session, and log in to ensure it is all proper.
Once logged in, you can leave it there or log out and leave the session at the password prompt. Either way, leave the session active and allow it to capture the output from the next reboot.
Once that reboot occurs, you can end the Serial connection and provide the logs to support further investigation.

Also provide applog.log, csc.log, syslog.log, msync.log and networkd.log from the Aux device.

Regards,

Sorry Guys, i was in Forced Holidays
i proceed with the Log Grabbing now.....BTW the Peer is in Hang, so basically if i try now to SSH directly on the Peer Device....all the options are in the state "Please try after some times. System is initializing"

AH!

i didn´t have time to search the into the menú....

You say there's a known bug causing this; can you give more detail?  Does it only affect XG330s?  Is there a workaround?

Guys the Sophos Support told me that is a KNOWED BUG that will be fixed with a new Firmware (for my XG the MR4), but the firmware itself is not available yet...

Hello Stefano,

Thank you for the follow-up!

I am not sure which Known Issue ID she mentioned, so I have asked for an update.

Regards,

Hello Bruce,

There is this Known issue ID NC-64907, but there is no specific appliance being affected by this.

There is a patch available and resolved on MR4.

Regards,

thank you Emmanuel, can you confirm that i am not able to download the MR4 from anyware at the moment?

Thank you in advance...

Hello Stefano,

At the moment MR4 hasn't been released. 
However since there is a patch available, I told the engineer assigned to your case to get the case escalated to get the patch applied.
