I recently noticed that for some reason we have a lot of forms that did not save to the repository as they were supposed to, so I have been going in and clicking the retry button on a few of them. After doing so I noticed that they had not completed after a few minutes and so I checked the Application Log on the Forms server. I am seeing a lot of messages similar to the following:

Does anyone have any ideas how to troubleshoot this? I have tried to restart services, the Forms website and App pool, but I still receive the same message.
