I noticed this too. While ops working, the InActConn is always changing too, if it's fixed, the ops is not working. >> And the traffic routed to each realserver didn't following weight I >> set, it's routed pretty much one to one.

Yes, latest git version. When CPS is changing, the ops works, or it's not. -- To unsubscribe from this list: send the line "unsubscribe lvs-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
