Okay. I'm glad to hear it. I'll close out this ticket then. Feel free open a new ticket if you encounter any new issues.

The above SMB problem did not appear in U2

Have you tested whether fixes in U2 have addressed this issue?

With U1 I was able to produce a crash in the SMB server (known timer bug) which stopped SMB transfer. With latest internal there was no crash.

On latest internal shasum for file with / without encryption is identical. Let me know if you want to verify the issue is resolved with an internal dev build. You can email me at awalker@ixsystems.com.

new debug has been uploaded

Just need to add in SMB global settings

aio max threads = 100
aio read size = 1
aio write size = 1
smb encrypt = desired

then enable SMB encryption in windows to reproduce the error
