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
Roger

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

The fix should be already implemented in the version you use.

Kind regards,

Juniper is sending me a new one, thinking it’s a faulty unit.
