Firepower showing error primary detection engine process terminated unexpectedly

[Day-dreamer]

Hi Everyone,

One of my sensor is showing critical error all the time as below picture . Does anyone know how to fix this ?

Thanks a lot

That's Snort crashing.

Are you running a current software release (like 6.2.3.5)?

Thanks,

I don't know how directly. I would go straight to a TAC case on this one. It may be a hardware issue.

After talking with TAC , we have detected snort process crashed and seems to be a bug here also
