Spec Reference:

Description

If a TBF is freed (e.g. caused by timeout or replacement), the dropped (unsent/unacknowledged) RLC frames are silently dropped. If an MS object is freed (TBF creation failed during the timeout interval), the dropped LLC frames are also not reported. At least counters should be implemented for these cases.

It's a violation of the spec. OsmoSGSN doesn't care, but if you interface with other SGSNs, they might expect to receive such messages in order to optimize their flow control and/or QoS.
