Wsfull from sort on disk

Hello,

I am trying to sort on disk but its resulting in wsfull.  I’m just using 

``symtime xasc path

I thought xasc could sort table on disk without loading into memory.  Any idea why I would get wsfull from this?

Thanks!

I believe the table has to be splayed to disk. Is your table splayed? (see https://code.kx.com/wiki/Cookbook/SplayedTables for explanation)
