I might be hitting PR1664302
keep in mind, I have another 7100 racked right beside this one with no
problems
me@lab-7100-2> show log messages | grep "cooling|shutdown"
...
Jun 8 20:23:23 eng-lab-7100-2 hwdre: HWD_COOLING_FIRE_SHUTDOWN_INIT:
Cooling zone fire action initiated !!
Jun 8 20:23:23 eng-lab-7100-2 hwdre: HWD_COOLING_FIRE_SHUTDOWN_SENSOR:
Sensor /Chassis[0]/Fpc[0] Sensor J2 Max Reading crossed fire threshold
temp value 136, driving chassis to shutdown
but i just now had someone pull the power cords since i couldn't console
in... so I don't know if this reboot reason is from the power cord pull
or the previous high temp shutdown PR condition
me@lab-7100-2> show chassis routing-engine | grep reboot
Last reboot reason power cycle
interestingly, the PR is said to be fixed in 22.2R2-EVO, wouldn't that
follow that it should be fixed in my version? 22.2R3.13-EVO
me@lab-7100-2> show version

Junos: 22.2R3.13-EVO

Hi
Some generic pointers here:
Checklist for Collecting Crash Data - TechLibrary - Juniper Networks
<https://www.juniper.net/documentation/en_US/junos/topics/task/troubleshooting/crash-data-collection-checklist.html>
show chassis routing-engine
What does "last reboot reason say"?
I would upgrade to 22.2R3, it's working fine for us so far.
Regards
