Sorry to be unclear about my code sample, the maCompetencyIndex is never
used. And the hang occure when using standard indexes. The more there
are indexes the quicker the hang.

From you example, and adapted to my use case I added a loop to stack
some object: 

I can stack 120 objects just fine. If I stack 150 objects it hangs, and
currently no OID/indexes files appear in the DB folder, just the
commits, object*, applied.* files and folder

|mc subMc|
mc := MagmaCollection new
       addIndex: (MaIntegerIndex attribute: #key);
       yourself.
1 to: 150 do:
	[:i | subMc := MagmaCollection new
 	      addIndex: (MaIntegerIndex attribute: #key);
 	      yourself.
	subMc add: i ->'subMc'.
	mc add: ((i +150)->subMc)].
Transcript show: ' Done '.
MagmaRepositoryController create: '/tmp/hilaireTest' root: mc


Hope we can find the issue
