3.1.2.2 Pending Request Cleanup Timer

This timer regulates the amount of time that the protocol waits before removing expired entries from the PendingRequestTable (section 3.1.1.3) ADM element. The server MUST maintain a per-call timer for each call to the R_StartReceive (Opnum 7) (section 3.1.4.7) method or the R_StartTransactionalReceive (Opnum 13) (section 3.1.4.13) method. This timer is set when a PendingRequestEntry (section 3.1.1.2) ADM element instance is added to the PendingRequestTable ADM element. The duration of this timer MUST be set based on the system configuration, which is implementation-dependent.<11>
