RT 4.2.11 Browser Reload Blocking session in Oracle

After upgrading to 4.2.11 we are experiencing a blocking lock in Oracle
after successfully logging into RT. When trying to reload from the browser
it seems the intial “select for update” is not allowing a subsequent update
to the session table.

SELECT a_session FROM sessions WHERE id = :p1 FOR UPDATE
UPDATE sessions SET a_session = :p1 WHERE id = :p2

Any ideas what could be causing this behavior?

The webserver is Apache on Linux and the database server is Oracle 12.1.0.1
on Linux as well.

Thanks,

Jeremy
