randomly(random hour/random minute) my freepbx server completly locks up(cannot even ping it). i have this on both an old machine, that ran great on an earlier version for at least a year.
thinking i have a hardware failure, i also have a ESXI server, that i was going to migrate to, but on a brand new, latest ISO download last night, it also randomly locks up to where the console doesnt respond, nor can i ping it. (different IP address)
That doesn’t mean a thing. The ISO could have easily been packaged with those versions. You have no idea when the code for the ISO was “frozen” for testing and packaging.
This goes for anything released as an ISO, it is not specific to FreePBX.
grep
/var/log/messages*
for events before and after it dies, it should still be there after the machine crashed
you muttered about esxi but nobody has any knowledge of the machine you installed it on, bad memory, bad disk, bad hardware are all possible culprits, as others have suggested please don’t be a dick (that REALLY is by contraction my job )
