Hey Dave,
If you still have the trace back, could you file a bug? I'd like to fix it
so that if this does happen again, reconnection works - sorry it didn't
this time, I know how much it stinks to lose wprk/time like that.

That is one way to fix this, yes, although maybe making sure the reference doesn't go out of scope would be easier?
I'll definitely make sure that it doesn't croak in the future (I believe I've sorted it out since I sent this email-- I did, in fact, do something dumb) but this bit took a while to run so if I _can_ fix the thing I have that'd be sweet. I did try re-attaching the parameter file, but it didn't seem to take-- I think I'll just punt and read papers today and re-run this analysis without the dumb-ness.
Thanks a ton! d.

Ah. I know what the parameter file _should_ be, can I go re-assign it to the clumps?

Looks like the reference is not to the data object, but the parameter file. From this context it's tough to see how that reference expired, though. It could have happened if something like this were done:
data = load("something").h.all_data()
or if you ha a pf variable that was not held anywhere else that then went out of scope.

Is there a way to reconstruct a bad data object? I'm making a bunch of clumps, but some how (unsure how right now) the weak reference to "data" on some of them is evaporating.
Thanks, d.
