RE: [HEADSUP] Upcoming GNU sort removal

Currently the sort structures in the sort utility use 32-bits counters. With Tb files, this may be the limitation point. I can take a look into fixing that.

And did it go much better with base GNU sort? It's quite an extreme

case... :) Multi GB is also rare not speaking about multi TB...



Yes. However my problem now is ZFS stability -- typically locking up, case example today:
