Hi all.

After upgrading from version 3.0.x to 3.5.x, i noticed on winbind logs this lines:

This is only an example, my logs are full of similar lines.
On version 3.5.4 and 3.5.5, after some days, winbind crashed with panic error, with version 3.5.6 winbind does not crash anymore, but idmap already registered continue to populate my logs.
Someone can tell me why and what this means?
Thx.
