I've never heard of the ability to access an external class without it being defined in the bigip.conf. Logically, I don't see how it would work. I think it would be better to have the BIG-IP initialize the class at start up, versus trying to load it every time that portion of the rule is executed.

 

 

If the class loads and works correctly with fewer entries, I think you can be reasonably sure that you're hitting resource limitations on the BIG-IP combined with how BIG-IP is accessing the data.

 

 

There have been a number of improvements to how external classes are handled in the upcoming 9.4 release, as noted in CR66389.

 

 

You might consider opening a case with support if you're interested in having these changes backported to 9.2.x.
