Symptoms

Suitably large GTM configurations can take longer to save to the bigip_gtm.conf file than the configured timeout.

Impact

Making numerous changes might lead to multiple instances of the save operation running simultaneously. Large memory consumption, potentially leading to a crash.

Conditions

This occurs when GSLB automatic configuration save is enabled, many changes are made that require configuration save, and the gtm.global-settings.general.automatic-configuration-save-timeout is less than the length of time it takes to save the configuration to file.

Workaround

Set gtm.global-settings.general.automatic-configuration-save-timeout to a larger value or disable automatic configuration saving for GTM / GSLB.

Fix Information

Simultaneous GTM configuration saves no longer occur, so memory is not consumed for them.
