Hi Marvin.. I suspect that this may be due to bug 6363519 http://bugs.opensolaris.org/view_bug.do?bug_id=6363519
Synopsis: SCTP must clear any H/W checksum flag in the inbound mblk before re-using it. The public bug report says little or nothing to relate this to your problem, but the internal evaluation does. A small extract of this: "If this mblk is sent to IP by the driver, ip_sctp_input() will not clean the flags and the resulting SHUTDOWN-COMPLETE chunk created by sctp_ootb_shutdown_ack() will have this flag set as well. This effectively results in an incorrect IP hdr checksum, which means the packet will be droppped at the other end." Can you see the SHUTDOWN-COMPLETE in snoop/ethereal on the Sun end ?? PS. the mail attachment is missing.
