Opened: Mar 28, 2021
Severity: 2-Critical

Symptoms

A sessiondb entry cannot be looked up.

Impact

The session db lookup failure leads to the establishment of a new connection, even though there is an existing connection to the pool member.

Conditions

A connection takes more than 5 seconds to establish. For example, in SCTP, the connection establishment might take more than 5 seconds with a maximum timeout of 60 seconds

Workaround

Increase the temporary timeout of the session db entry to 60 seconds.

Fix Information

None
