Description

When a user aborts a a session with a long-running commit, the clean-up process can take a very long time. During this clean-up phase, commit/rollback statements from other sessions may be blocked. This can result in delayed or blocked logins, making the system appear to be frozen.

Workaround

Avoid triggering session terminations that perform extensive commits.

Fix

Aborting sessions with long-running commits no longer blocks other commit/rollback operations and no longer results in extended login times.
