Hi All,

I have run Open vSwitch-1.7.1 testsuite. All test pass except NetFlow flow
expiration.The details of log file is as follows:

> header: v5, uptime 93, now 235.188028743, seq 0, engine 2,1
> rec: 192.168.0.1 > 192.168.0.2, if 1 > 65535, 1 pkts, 60 bytes, ICMP 8:0,
time
 90...90

time 110

457. ofproto-dpif.at:936: 457. ofproto-dpif - NetFlow flow expiration
(ofproto-d
pif.at:936): FAILED (ofproto-dpif.at:963)

 I have also applied the patch
http://openvswitch.org/pipermail/dev/2012-August/020322.html
but still NetFlow flow expiration test failed.

It seems from the packet that there is some timing issue. Kindly guide me
how to solve this issue.
