[Swift-devel] Montage workload

[Jonathan Monette]

So this looks like a problem in the Swift code.  The hang checker is activated at the start of the execution which is not good.  Could you point me to where you ran this? Was this on surveyor?  If it was not on surveyor I can give it a try.  It looks like the projection phase is trying to project empty files.   This could be due to the files actually being empty(I sent corrupted data) or Swift cannot find the files but ran mProjectPP anyways.
