On Friday 15 may 2015 I was able to successfully send 3000 flows to OF switch and via flow statistic reply store it to operational datastore.

Today I checkout back to my built (when it was possible) 39ca97e292ee5348cac005fe35b7973dfe8a1627 (Ensuring exclusive access to flow registry.). I built it again and currently I am getting lot of warning messages in log:

2015-05-18 14:03:55,393 | WARN | entLoopGroup-8-3 | TransactionProxy | 179 - org.opendaylight.controller.sal-distributed-datastore - 1.2.0.SNAPSHOT | Failed to acquire operation permit for transaction member-1-txn-81733

I suppose that problem could be in controller. I will try to build caraf with artifacts from friday.

The same log entry is observed also with
odl-openflowplugin-flow-services-rest
feature installed.

Could we please add steps to reproduce in here. I am assuming we want 25 switches connected and then the flow blaster script to be run.

The links to the jobs are not working.

Links are not working, because jenkins' history "moved" forward. In general you can take any later job results

Regarding steps to reproduce. You can take any build with "yellow" ball and check it's robot results. The test "Are Switches Connected" is failed, because 25 switches managed by mininet are not present in the operational inventory.

So steps are, connect 25 switches with mininet and check operational inventory nodes.

steps to reproduce:

• start openflowplugin karaf distribution
• feature:install odl-openflowplugin-flow-services-rest-li
• start mininet (with e.g. one switch)
• PUT batch of flows (in my example 1000 flows see enclosure)

Then in karaf log starts to occure following warning repeatedly
2015-05-19 08:46:03,754 | WARN | entLoopGroup-8-8 | TransactionProxy | 182 - org.opendaylight.controller.sal-distributed-datastore - 1.2.0.SNAPSHOT | Failed to acquire operation permit for transaction member-1-txn-187409

Other symptom is problematic connection between controller and switch. Controller gradually stops to response. At the begining controller response on OFPT_HELLO but in the end no response from controller is received.

When inserting flows one by one (tested on three flows) then this problem doesn't occure.

after merging this patch
https://git.opendaylight.org/gerrit/#/c/20680/

new problem has occured.

When config datastore contains batch of flow (in my L2SWITCH-40) they are successfully sent to device after it turn on. Also statistics bring this information to controller but it isn't written to database.

Karaf log contains flooding of warn logs
2015-05-19 13:05:12,395 | WARN | entLoopGroup-8-5 | TransactionChainManager | 198 - org.opendaylight.openflowplugin.impl - 0.1.0.SNAPSHOT | failed to put into writeOnlyTransaction : Previous transaction member-1-txn-407757 is not ready yet

the initial problem is the problem of ovs versioning discussed in
https://lists.opendaylight.org/pipermail/integration-dev/2015-May/003282.html

the last problem mentioned by Jozef does not happen at this time

therefor "closing" the bug
