commit 725d3a0d31a51c0debf970011e05f585e805165b upstream.

Fix stuck sessions in get port database. When a thread is in the process of
re-establishing a session, a flag is set to prevent multiple threads /
triggers from doing the same task. This flag was left on, where any attempt
to relogin was locked out. Clear this flag, if the attempt has failed.
