I am saying that I cannot make it work even with 7GB of RAM
free/available...and I also have plenty of swap space from what I can tell.
Sounds like this should be plenty of RAM to list 66MM objects (66154585
instances to be accurate). But maybe I am wrong...

No problem. It usually takes me some time because I must stop everything,
restore from backup, modify the listMethod via topaz with SystemUser, then
run update code... then as soon as it fail I must revert again with the
"corrected" extent so that the system is not that long in a bad state...
But still, if this is if help to you by any means, I am happy to continue
trying.

My offer is still valid if you want to enter via web and have an use some
"code workspace" I have or the seaside debugger etc. I could also open log
the exception in the object log if you want. Or I could temporary open a
port in the firewall in case you want remote-gemtools (but that is very
very slow). But as said, we should coordinate the date for this.

Cheers,
