Memory leak in wr_urldbd, leading to a stuck or inconsistent state.
BIG-IP with Service provider configuration which tries to achieve URL Categorization of subscriber traffic. SP DAG is configured. Most requests are being processed by the same TMM.
Traffic disrupted while tmm restarts.
Fix makes sure wr_urldbd IPC message queue pileup does not happen, hence memory leak will not happen.
