On my home file server for example, which is not connected to the

EL5... how modern... from a production application server VM, not

This one has to be hard reset every day or two (virsh reset rhel2.1)
since the bridge to the guest just dies randomly, and a reboot inside
the guest hangs hard before finishing the reboot. The hard reset has to
manually load the ethernet kernel module after it's booted up so far; if
the ethernet module loads too soon it will never connect.... haven't
found the reason for that, either, just run a pinging script every
fifteen minutes on the host to check for connectivity and 'virsh reset
rhel2.1' when it fails. The appserver is hard reboot resilient, and the
software does a very specific task, and there's no budget for a
rewrite. At least I did upgrade it from Red Hat Linux 5.2 a couple of
years ago (the RHL5.2 box, an old AMD K6/2-450 with 128MB of RAM, ran
almost continuously for 20 years).
Thanks, CentOS!
Indeed!
You have clearly had more success with the longevity of your hardware
than me. I was plagued with expanding capacitors about 15 years ago
which killed off most of my hardware at the time, and the replacements
were taken out of service as they subsequently died meaning I'm
exclusively running el7|8 now :-)
