Dear Jason,

from the looks of it, it seems like a memory issue (GC overhead limit exceeded). You mentioned working with admittedly rather large TTCN-3 code base which would also suggest potential memory issues. The general remedy is trying to increase the memory settings even further (-Xmx1024m or more). Your intuition is otherwise correct, this is indeed one of the intended functionalities of TRex. But before you perform any of those actions, you need to make sure that initial processing is finished (depending on the codebase size it may take a few minutes to parse and index all resources). 

It could also be a bug of course, and I will have a look at this as far as time permits, but generally memory consumption with large test suites is a known limitation of the current implementation and careful memory selection mostly helps (~2 GB for 200 000+ LOC TTCN-3 code, for example). 

Best regards,

Philip

Eclipse does not return any results nor following through the code as I would expect it to do so…

Dear all
 
I am trying to use the T-Rex build-in functionality “open declaration” and “find references”. Nothing seems to happen and after a while (hanging Eclipse) I get the following errors:
 
<Picture (Device Independent Bitmap) 1.jpg>
 
I am using the plugin of T-Rex on Eclipse 3.7.2 . As recommended, I have increased the mem usage to 512m, but still seems to have no effect. I am using Subclipse for my TTCN script repo (which is relative large) and the default Java perspective (if that has anything to do with it).
 
What I want to do here is to enable Eclipse to ‘resolve’ functions, declarations etc so that I can navigate through the code quicker – without having to manually look where a particular function is stored. I presume T-Rex should allow me to do this, right?
 
Any thoughts that might help me figure what’s wrong here?
 
Cheers
Jason
