[GSLL-devel] Bug or feature: grid-map and complex type destinations

[Liam Healy]

That one I recognize.  By any chance do you have your files on a
server (like NFS)?  If so check to make sure the clocks are
synchronized.  If the asd file has a time in the future, ASDF goes
into an infinite loop.  We had an NFS server that had a significant
clock drift, and I would get bitten by that a lot.  I posted a bug to
the ASDF list but no one responded.
