Reconnect logins for sessions which are already running may cause logins to hang.

Detail name	Value
Changelog Number	30115
Type	Bug
Status	Open
Affected Versions	Exasol 2025.1.0, Exasol 2026.1.0

Description

When a session is connected and running, the driver may automatically perform a reconnect if it detects that it has been disconnected for some reason (e.g. network issues). During the reconnect process, the login procedure may hang. If this occurs too often, then all logins-even for new sessions-can become blocked.

Workaround

Restart the database.

Fix

The issue will be fixed so that logins for reconnecting sessions do not hang and/or block other login attempts.
