Hi All,This might be OK. Only every other packets is SACKed immediately...
Some times in the load test we have observed SCTP-Client Application is sending ABORT message.
In the SCTP-logs we have observed the following:

When refered the code, we have seen streamengine function : is sending ECC_PROTOCOL abort.
Please help me, why this error comes. Is it congestion on the SCTP- Client application or SCTP-Server application is sending some wrong values.

Nigar
