What is to understand? It looks like some class of yours is calling execute on a PreparedStatement. Is there a problem with the query?

it is a timeout message of you stuck thread. It can be even a long-runner query and the message is being thrown before returns it.
if it is necessary then you can set a longer timeout.

As you know can be several issues, therefore try to execute the same SQL queries outside of WLS, and check if you can replicate the issue.
I agree. Here's the link:
