formName: ajax

formAction: fa_loadGridDataHistory

serverStatus: false

serverStatusText: CriticalException

errorCode: 6

These are the error codes that I get randomly while working on a sheet or when saving. Is this due to multiple changes happening to the sheet at the same time? Or is the sheet handling too much data?
