On some large LTM configurations, validation errors that occur during import/reimport can lock the user out of the system. The root cause is the large amount of memory required to back out the changes to the configuration, leading to an almost continuous execution of the Java Garbage Collector (GC), which stalls the system while trying to free memory.
System locks out users and becomes unusable for long period of times.
Large LTM configurations, import or re-import a device triggering multiple validation errors.
If this condition is encountered, restart BIG-IQ. Then, fix the BIG-IP configuration that's triggering the validation errors prior to attempting to import or reimport the BIG-IP device.
The transaction subsystem has been refactored to reduce the amount of memory needed to roll back.
