We have received reports that Checkpoint UTM-1 devices performed an unscheduled reboot. The initial reports we got indicate that the device rebooted at 10pm EDT on Oct. 30th, which happens to be midnight GMT.

There are several posts on Checkpoint support forums verifying this issue [1][2].

Checkpoint confirmed this problem [3] . According to Checkpoint, the reboot happened because of a timer that will roll over every 13.6 years.

This may be a 32 bit timer counting 1/10 seconds. 429 million seconds works out to just about 13.6 years.
