What does invalid database_id mean?

[Sep Ng]

Every once in a while on my aolserver logs, I find this error and I'm not sure what it means.  Typically, I see it when performing a database operation and then aolserver drops into an error like:
invalid database_id: nsdb0

Is this related to another log entry: max connections exceeded?  Is the database handle not valid?

Hoping someone can shed some light on the nature of this error.

Thanks!

This means that there is no handle associated with the key "nsdb0". I'd
guess this is because something called [ns_db releasehandle] when you
weren't expecting it, but it's also possible that the handle was passed
to a different interpreter (e.g., through a nsv) rather than acquired
with [ns_db gethandle], which won't work.

It's unrelated. "max connections exceeded" happens when a conn thread
has served as many requests as it is configured to do and exits.

Thank you for your explanation Jeff.  I will continue to look for where the handle was released.  It must have happened on the same thread, yes?  The same thread that handled the request, yes?
