Opened: Dec 06, 2018

Severity: 3-Major

Symptoms

Long-lived connections get a reset and must restart.

Impact

Results in a TCP reset. This causes long-lived FTP connections to reach a different tmm on a different blade, and the connection is reset due to no flow found for ACK. The blade never goes down.

Conditions

Clustered Multiprocessing (CMP) system state change.

Workaround

Set the db variable iprep.autoupdate to 'disable'.

Fix Information

None
