We regularly get errors with scripts timing out. Netsuite say it is the script but it happens with different script vendors, Avalara, our own, and even some netsuite bundle scripts. We have SuiteCloud+ and plenty of capacity. Anyone else experience anything similar: {"type":"error.SuiteScriptError","name":"SESSION_TIMED_OUT","message":"Your connection has timed out. Please <a href='/pages/login.jsp' target='_self'>log in</a> again.","id":"","stack":["createError(N/error)","AVA_InventoryTabBeforeLoad(/SuiteBundles/Bundle 296604/AVA_UES_InventoryItems.js:26)"],"cause":{"type":"internal error","code":"SESSION_TIMED_OUT","details":"Your connection has timed out.

That error is a session timeout, not what I'd consider a script execution timeout. Perhaps Avalera is trying to reach out somewhere that's not responding?

@PlanetJupiter I wonder if this comes up when a user returns to an open tab after their session has expired and attempts an action that executes some script. I see the same thing in our logs frequently, but no one ever reports an issue.
