I found the solution. I’ve replaced softflowd with pmacct (which also based on
softflowd code) and disabled in pmacct promiscuous mode. The sequence errors
has gone!

When softflowd export flows as v5 there are no sequence errors. I tried play
with buffer size with no success. Where is error? How can i solve this problem?
Thanks.
