Hello everyone,
We have the problem in our SharePoint 2010 environment that the Global navigation disappears randomly on some sites - in the last 3-4 weeks it happened around 2-3 times. We I go to Site Navigation settings and just click "OK" (without changing
anything), the navigation comes back on this site. And when I flush the site collection object cache, then the navigation is displayed correctly on all sites again.
We are using the standard top navigation control, but we have increased the display levels in the masterpage (Static=2, Dynamic=3) because the customer wanted it.
It is not clear what leads to this behaviour although we suspect that it happens after an application pool recycle (for example after a deployment). But we cannnot confirm it as it does not happen after every application pool recycle or deployment.
Seems like the object cache goes into an inconsistent state as a result of something, but its not clear what causes it. Would be grateful for any ideas as to what could be leading to this behaviour ...
Thanks and regards,
Simranjeev
