There is a race condition when cancelling requests + during a high load situations which could lead to + spurious (megaco internal) messages beeing sent to + user processes. When a request is issued using + megaco:call, + which returns only after a "reply" can + be delivered, the request timer might expire + during the cancelling of the request, which will cause + megaco to attempt to deliver the timeout info, which + will result in the spurious message. + This problem has now been eliminated by introducing + a proxy process, which simply dies when the "real" + response has been delivered.

+ Fixed bugs and malfunctions + + +

Megaco re-transmission loop, when setting the long request timer + to an incremental timer. Megaco changes to the long request timer + when receiving an pending message (after having sent a request). + Each time the (long) timer expire, it will incorrectly result in + an re-send of the request. This is meaningless since we know from + the received pending that the "other side" has received the request + and is working on it. Furthermore, when in this case the "other + side" receives the request again, it will send another pending + message. Receiving a pending message in this case will + restart the timer (reset it to the initial values). This + means that the timer will actually never fully expire and the two + stacks will continue to exchange request/pending messages for as + long as the "other side" is working on the request.
