After the script has run for 10 minutes or so, it just seg faults. The script itself takes big amounts of data, and throws them into objects in an array, then when done it passes them on to a "saver" object that aves the object in another database.
This happens at the end (it seems) of running through the array and plopping the objects into the database.

Here's the backtrace:
Program terminated with signal 11, Segmentation fault.

Thanks

Hi,

I dont serialize any data.

What happens is that I get lots of data from an Oracle database, then for
each row i make x objects (objects being product (if!isset), item, unit,
contry and so on), after having made all the objects i throw them into an
objectsaver that saves the object data (not the object, just the data) in
another oracle database.
We might be dealing with 10K objects taking upwards 20mb mem. It is only
when its saving the objects in the oracle database it segfaults -- which
means that ALL objects HAVE been created, and are being saved.

If theres anything I can do, please tell me, and I will happily subject
myself and/or my little php fellow to all sorts of sadist attempts at
squashing bugs :)

TIA.

Kind regards,
	David.

Do you have this problem with 4.1.0?
