Thank you for explanation Luis. I missed step 3 when I was going through test
report. At least now I know where to search for issue and after this last one
will be fixed, single layer model implementation will be finally finished,
because other than this it is not causing any more regressions
Hi Santosh,
Couple of questions -
a) Does crash happen instantaneously – I mean within shorter intervals or
degradation is progressive over time ?
b) since you emulate the flaps, is it possible to control the frequency of
flapping with your emulation ?
If (a) holds true or (b) is
Hi Anil ,
Thanks for your response ..
We are running with following memory option , I think which is sufficient
for ODL instance having 150 OF connection.
-Xms128M -Xmx31393m -XX:MaxPermSize=15696m
Any thoughts on this ??
We would be trying to recreate this issue in order to get heap dump
Hi Santosh,
Looks like your controller crashed while spawning a new native JVM thread,
because your JVM Is out of native heap space.
Can you increase your native heap space and see if you still hit the issue
(it might take longer to recreate the issue). Meanwhile if you have the
heapdump, please
Hello openflowplugin developers ,
I have been using lithium release of opendaylight. We are seeing ODL
crashes with error mentioned in the subject line , when we test the
scenario of frequent connection flap .
If this issue has been already addressed as part of the latest release ,

Hi Tomas,
The reconciliation test does the following:
0) Enable stale-flow entry feature (otherwise step 5 will not work)
1) add 2000 groups + 1000 flows (+10 table-miss)
2) Disconnect network
3) Remove 20 groups + 10 flows
4) Reconnect network
5) Check groups and flows are deleted from switch
Hi again Luis,
I managed to get single layer serialization to pretty stable state, but I have
1 quick question, and hopefully you will know the answer.
According to test result from flow-services CSIT here:
Hi Muthukrishnan,
there is no golden standard behind this value. Setting it to 100ms or even
lower value will result into low latency system but this also decreases
throughput of system.
If you have few switches and little no big requirement on flows per second
throughput then 100ms might

Why is it happening in Issue 1?
