Opened: Dec 02, 2022 Severity: 3-Major
If GTM objects larger than 16384 bytes are created, then the GTM sync process will not complete. In addition, the gtm_add process (which requests a GTM sync for all objects) will not complete. Following is the symptom for gtm_add: After "Retrieving remote GTM configuration...", the process will pause for 300 seconds (5 minutes), and then exit, with a message "Syncer failed to retrieve configuration". For a normal GTM sync, where gtm_add is not being used, the symptom is that the synchronisation of configuration changes is not working.
Unable to complete GTM sync, unable to add a new GTM into the sync group.
The presence of any MCPD object in the GTM configuration (/config/bigip_gtm.conf) which is larger than 16384 bytes, for example a large GTM rule. Note: The GTM iRules are distinct from LTM iRules. Only GTM objects, such as GTM rules (applied to wideIPs) are relevant to this issue.
Reduce the size of the problematic object to lower than 16384 bytes. For example, if the issue is with a GTM iRule, then try removing comments, blank lines, or unnecessary log statements that do not affect the functionality of the rule.
