I had selected that an assignment should be mass regraded. Web-CAT happily processed my request and started grading away. I then did a \\\\\\\\\\\\\\\"spot check\\\\\\\\\\\\\\\" on the grading and realized that I had made a mistake in one of the settings for the regrade, so I went back into the assignment and changed it. However, I did not stop the mass regrading process. After I had clicked \\\\\\\\\\\\\\\"Save\\\\\\\\\\\\\\\" after making the change, Web-CAT crashed. We have Web-CAT installed on our own server and it had to be rebooted manually. The crash was caused by bad \\\\\\\\\\\\\\\"user behavior\\\\\\\\\\\\\\\", but it might be something that users should not be able to do. I have attached a file with the last chunk of the error log that was generated when the crash occurred.
