Null Pointer Exception on Gateway Startup

Ignition
1

My colleague shutdown his Ignition gateway before he went on vacation, and when he tried to start it back up and connect the gateway reports that it is faulted.

Attached is the last few days of his wrapper.log. He cannot access the gateway webpage and cannot connect to the project with designer.

It appears to perhaps be related to corrupted XML named query files, but I’m not sure what the best path to resolve is. Delete the files perhaps?

Somewhere, there’s (at least one) named query with a data.bin file that’s 0 bytes. If you care to be surgical, you can go through data/projects/$projectName/ignition/named-query/$paths in the installation directory, looking for that file. Or you can delete all the named-query resources (per project).
