Impact

TMM fails

Conditions

Using external datagroup, rapidly creating updating and then deleting it.

Workaround

Allow TMM enough time to finish processing external data-group before starting another operation. Depending on the size of the datagroup anywhere from 1s to 10s or more may be needed. The LTM log can be examined for the create/finished message to help determine how much wait time is required.
