When trying to access the Job Queue Status page or running a Document Package, the page fails to load and the following error occurs:
Maximum view state size limit (135KB) exceeded
Navigate to the View State tab and ensure that the elements on the page have not exceeded the maximum view state size of 135KB.
Salesforce allows Visualforce pages to have a maximum view state size of 135KB. Note that a smaller view state size generally means quicker load times. It is a best practice to avoid pushing an excess amount of data in the page.
