I’ve been running a number of Vyatta routers that were later upgrade to VyOS. Things have been working great with them until I upgraded to Helium. Note that this has also happened with a few Hydrogen upgraded to Helium routers as well. Now I have an issue where they randomly stop accepting any shell input. Everything else runs perfectly and I can leave the router running for weeks in this fashion. SSH still responds but as soon as I enter the username and password it will just sit there. Same response from console as well. To get back to a working console I have to power cycle the VM. It seems to happen after a random amount of time as well so sometimes it just takes minutes other times it runs fines for days. I’ve exhausted my Linux troubleshooting capabilities on this as I can’t find anything being referenced in /var/messages. I haven’t tried making any fresh builds of the VMs yet to see if it is just an issue with upgrading. I can confirm never running into this issue with Hydrogen though.
Any ideas to set me on the right track for getting this issue squashed?
