The effective receive-chunks, transmit-chunks, in-streams, and out-streams parameters in SCTP traffic do not match the settings from the configured SCTP profile: -- The in-streams setting alters both the in-streams parameter and the tx-chunks parameter. -- The out-streams setting alters both the out-streams parameter and the rx-chunks parameter. -- The tx-chunks setting has no effect. -- The rx-chunks setting has no effect.


Unexpected SCTP parameters are negotiated on SCTP connections.
