I'm surprised that we haven't heard about this as a problem before. A realserver crashing must happen often enough that someone else has already seen this. > These numbers remained the same for 10 or more minutes and > then ActiveConn started decreasing slowly. I thought the timeout were about 2mins. Would changing them to 2mins help (it's one of the options to ipvsadm)? > Once the ActiveConn was lower than the other realservers > had, new requests started to reach the server and > InActConn increased from 0.

Neither LVS restart or > "ipvsadm --zero" helped. ipvs keeps its state tables so it doesn't mess with any ESTABLISHED connections.
