Running Script Causes loss to gateway

Ignition
1

I have a user that receives a gateway loss connection when clicking a button with a script that loops through and executes several insert statements. then when the user tries to launch the project off the gateway page the user receives a cannot connect message.

when I run the script from my computer i do not receive a gateway loss message.

here is the java console when trying to launch the project again.

I’m thinking something’s up with the network between that client and the gateway. That log shows a variety of transient networking errors (unexpected end-of-file, connection resets) that go away after a retry. I’dtry testing network cables, switches between this client and the gateway.

I have found some time to try testing out different scenarios. The problem only seems to occur under a specific username. Which computer and location do not seem to matter. Any other users do not have this problem when running the same script.

I am guessing it is something in the specific users profile. any ideas of what steps I should take?

4

I cannot think of anything specific to a user that would do this. It’s got to be something with your domain?

5

Is there a difference in permission levels between your problem username and the others?
I mean windows permission levels btw.
You might try running filemon as that user and starting the project. Look for access denied events on cache files.

  1. Are you using roaming profiles?
    1a. Is there anything else obvious about that users permissions from others?
  2. Try logging on with that user, opening the Java settings from the control panel. Clearing temporary files, then manually setting the location to a folder on the local hard drive that the user has full access to. Launch the client and see what happens.
