Objects allocated to SNADS

Over a year ago I lit up an unused ethernet port for external telnet access and in the process managed to create an open relay that lasted about a day before a slow system and rapid loss of disk space alerted me to the problem. There were tens of thousands of spool files and even after cleaning up I felt like there was still some lost space. But my posts here and actions taken seemed to make little difference. Since then I have upgraded this customer from V5R4M0 to IBM i v 7.1. During that process done earlier in the summer and which took me over a weekend, I noticed that the IPL step that showed SNADS recovery (or something similarly named) took hours to complete. I also just ran a RTVDSKINF and PRTDSKINF on this system and it shows the following:

SNADS and object distribution 14.93% 73762.36MB

73 gig allocated to SNADS ! They don't even use SNADS and all my probings have failed to turn up just where this stuff hangs out. My guess is that this is collateral damage from the open relay.

Is there any way to find out WHERE the PRTDSKINF report pulls the objects from for the "SNADS and object distribution" category? There is a bunch of stuff in a library or folder that I would love to finally get rid of!

Thanks!
