** Using WeBWorK **

Hi All,

A couple of years ago, I posted a similar problem to what I'm having right now.

Randomly during assignments, students will hit a submit button or try to view a question and their page load will time out. If they hit the back button and resubmit again, it will work (this occasionally takes a few tries). I've also notice this timeout issue randomly happen when trying to log in to a course.

Here's what the error logs look like upon one of these occurrences (sorry for the log dump!)

Michael Gage responded to my previously posted question here: http://webwork.maa.org/moodle/mod/forum/discuss.php?d=2552

I've restarted apache and the webserver multiple times with no luck. Is there any way to verify that all of the perl modules are properly loaded? I don't get any error messages upon restart of either the server or apache. We've got a final exam coming up this next week in WeBWorK and now it decides to act all wonky! Argh!

Thanks for any suggestions!

Tony
