Garbage collection in VW7.7nc

BREITH Karl-Albert (AREVA)
Garbage collection in VW7.7nc

In VW7.6, when I closed my application and performed a global garbage collection,
the instance with all variable and so on is completely gone.
In VW7.7, the instance stays alive and blocks a lot of memory.
Inspection of the reference paths - aborts.
Inspection of owners brings a long list.
How can I determine who really holds the instance ?

Karl

Re: Garbage collection in VW7.7nc

If the only change is between 7.6 and 7.7, my guess would be that your code is using a variable which has been removed, and so an undeclared is holding onto your application. Check the undeclared list.

Other than that, reference paths is your best bet. How does it abort? I'll guess it might be running out of memory. Increasing the memory settings might make it succeed, or it might be that there is something circular in there that it can't handle. When it aborts, it might be useful to look at what it's done so far. Or with inspecting owners, you may be able to narrow down the list, but that can be a bit tricky.
