I am using redundant Ignition servers and I am running into a problem where my Ignition on my primary server hangs.
When I view the status of the service on the primary server in a command line (service ignition status), it shows that it is running. I can not get to the gateway webpage on the primary, and the gateway webpage on the backup does not show the primary as running. The backup is active and the fail over works.
I am using Ignition 7.5, running on SuSE Enterprise Linux 11. The Linux servers are running as VM’s under ESX 5. They are located on separate physical servers.
This has been a very stable setup that we have been running for about a year. I have seen the service hang twice in the last week.
After the first time I went through the wrapper.log and tried to clear up any errors that I could.
This time there is the error:
