Regarding your paging ASD problem ...

This is normal.

The ASD evaluation function runs in a COMPUTE process. Try forking off a
compute process (e.g. run 'asdfly -m38').

Historical leftovers. It's not used any more.

I am not sure about these. Disk space shortage ?

Can you bring up the scene graph structure ? Is there an ASD node on the scene
graph ?

These look normal.

This happens when you don't fork COMPUTE. It is a bug. However, not forking
COMPUTE is not a good idea with ASD so this bug is a low priority one.
One additional note: Building paged ASD models with pfdBuildASD requires that
your entire ASD (all the pages) fit into memory+swap on the machine that
creates the pages. There is a newer tool called ASDGen that builds paged ASD
models and has a fixed memory signature. You can find information about it
in the info-performer archive. The source and a README for ASDGen are under:
