During the last reproduce this issue, the client/server LRO/TSO with default setting, I didn't change that. Then I disabled the DSACK and SACK in the server side(freeBSD), the client = was a normal Centos VM. After disabled the DSACK and SACK I can't reproduce this issue with more than 20 times test. --=20 You are receiving this mail because: You are the assignee for the bug.=
