I'm wondering if the LMDB database has been tested on HP-UX with the Itanium processor?

We are trying to use the database there and are seeing strange errors that don't occur on other platforms. Examples are assertions when trying to do cross process access and values not making it into the database correctly.

I can provide more details, but I thought I would ask about the current status first.

What OS revision are you using? Please provide full system description.

Have you had a chance to test it out? If you don't have access to that HP-UX version, we might be able to get a temporary login for you, Howard.
