An attempt to send an SS7 M3UA/ENUM DATA message has failed. The message has been discarded.
For SCTP, Possible reasons for the failure include:
The far-end is slow to acknowledge the SCTP packets sent by the MP server, causing hte MP server's SCTP send buffer to fill up to the point where the message cannot be queued for sending.
The socket has closed just as the send was being processed.
To Troubleshoot:
Check the event history logs at Main Menu > Alarms & Events > View History for additional SS7 events or alarms from this MP server.
Verify that the adjacent server on the signaling gateway is not under congestion. The MP server will have alarms to indicate the congestion if this is the case.
