Well, no more idea to share (except maybe that the restore process is
hanging somewhere, any strange information in call stack and job locks?)

For the records (by mistake, I sent my previous mail directly to Rob in

Trying to restore one IFS file, not that big (well when you think of

the

system as a whole that saves in under 45 minutes).

Started about 10:35:34. It's now 12:34. Two hours.

Do the TAP files ever get updated during a restore?
