FTD 2110 issue

[alex_bsb_by]

I have two FTD 2110 devices. There are in a high availability pair.  Sometimes they switches automatically for the reason: Inspection engine in other unit has failed due to snort and disk failure (detailed information in the picture).

 Cisco Fire Linux OS v6.6.0 (build 37)

Cisco Firepower 2110 Threat Defense v6.6.0.1 (build 7)  Cisco Fire Linux OS v6.6.0 (build 37) Cisco Firepower Management Center for VMWare v6.6.0.1 (build 7)

Could someone help me?

That can be the result of hitting a bug causing Snort to fail. The disk issue may be more concerning. I would recommend upgrading to the current recommended release (6.6.4) and seeing if the issue persists
