Pixhawk-Mini crash due to a glitch in embedded hardware?

Hey everyone,

I’m having weird issues with the Pixhawk-Mini runing ArduCopter 3.50_RC4.

I’m attaching a log of a crash that caused by what I believe was a glitch in time of the embedded hardwere.

You can see in the attached image of a TimeUS log that point on a glitch in time stamps.

What is causing it?
Did anybody ever seen this things?

Thankes, Gal.
