Last Modified: Sep 13, 2023

Affected Product(s):

Known Affected Versions:

Fixed In:

Opened: Jul 18, 2019

Severity: 3-Major


In device group has enabled 'save sys config' for all auto-sync operations using the following command: modify cm device-group name save-on-auto-sync true Warning: Enabling the save-on-auto-sync option can unexpectedly impact system performance when the BIG-IP system automatically saves a large configuration change to each device.


Configuration is not saved, which leads to out-of-sync condition.


-- The save-on-auto-sync option is enabled. -- Device has large configuration, such as 2,100 virtual servers and ~1100 partitions


You can avoid this issue by using manual sync instead of auto-sync, or by not enabling 'save-on-auto-sync'.
