[4.1.9-T6] samba crash and general feedback

I had previously upgraded the Samba on my ReadNAS Duo v1 running 4.1.8 from v3.0.x to v3.6.3. This was to fix intolerable performance issues when syncing iTunes with the Music Library hosted on the ReadyNAS using both 32-bit Vista SP1 and 64-bit Windows 7. My sync times went from 3+ days to less than 3 hours. A separate use case that was not working well was that my husband's MacOS laptop's Time Machine application could not see the ReadyNAS. It was while investigating manually upgrading that package that I saw this beta release.

Interested to try this beta so I could potentially have a supported solution, I downgraded the Samba back to v3.0.x and verified the performance problems came back. I then tried the 4.1.9-T6 beta image. While the latter use case involving Time Machine was fixed, the former case with iTunes and general Samba browsing got even worse.

Before I had settled on upgrading the ReadyNAS' Samba to 3.6.x, I had tried 3.5.x. I found that it's SMB2 implementation wasn't complete enough to solve the iTunes issues. It's possible that since 4.1.9-T6 is using 3.5.x, some of my problems are coming down to that. Either way, I'm happy to provide any logs or even remote shell access so you can take what has worked well for me and deliver it to the rest of your customer base. As I mentioned before, if you guys are in the SF bay area, I'm happy to bring the NAS into your offices to demonstrate.

I hope this is clearer than my earlier brain dump :)
Thanks!
