BRSX computer restarted

Dave noticed that there was an error light on at the BRSX Beckhoff box. Looking the the event logs with Carlos, we found some software errors that we suspect are responsible for this, shown in the attached screenshot. This seems to happen frequently with BRSX (I haven't checked BRSY yet, but we found the light on at the chassis at EY some time in December(?) as well). We cleared this by restarting the BRSX machine, but we aren't sure what the cause is or why the chassis light came on because of a software issue.

TWINCAT error codes reports the following for error 0x4225:

Drive not ready during axis start

During an axis start it is ascertained that the drive is not ready. The following are possible causes: - the drive is in failure state (hardware fault) - the drive is in the starting-up stage (e.g. following an axis reset preceded by a hardware fault) - the drive has not been enabled

Remark: The time required for "booting" a drive after a hardware fault can amount to several seconds.
