Intermitent problem with activities loading

[GoogleCodeExporter]

What steps will reproduce the problem?
1. I cannot reproduce the problem
2.
3.

What is the expected output? What do you see instead?
The expected is Activity and we get empty activity sometimes

What version of the product are you using? On what operating system?
Course Builder 1.1.0. Windows

Please provide any additional information below.

We have a course builder course with 800 students running and they consistently 
report that the activities sometimes don't load. They get all the base elements 
of the page but the activity part is empty. The problem is solved reloading, 
but some of them don't try, think that the activity is empty and report it in 
the forum. Seeing the number of reports it doesn't seem to happen very often 
but it happens.

I myself have experienced it in some occasion but I am not able to replicate 
it. Any ideas of what might be happenig? Can it be a problem of the javascript 
that constructs the activities pages? Can I change something in appengine 
configuration to avoid it (I have put a couple of resident instances and  
enabled PageSpeed Service but it continues to happen).

Thanks a lot for filing.

This is an old ticket, and we could not reproduce the issue, including in the 
most recent release of 1.7.
