We have a customer who is still on gateway version 7.1.1 and they have a recurring problem where one of their clusters fails to do a normal reboot after a patch is applied. Without patching a reboot works fine, but after applying a patch the shutdown procedure seems to hang. Their other clusters are working fine.
It's not high priority for them and they hope the issue will be resolved once they can finally upgrade to a recent version, but I though I would just ask around if someone has seen similar issues and if they have found fix for it. I have attached a screenshot of where the shutdown hangs. They have waited for about 30 minutes until finally doing a guest restart from VMWare. After that the gateway runs normally. They couldn't find anything in /var/log/messages.
