[OPNFLWPLUG-392] [LithiumBuild3335] Controller Crashed after making nodes REST call when the topology had 2 switches and 2k hosts.

Mon, 27 Sep 2021 09:01:27 +0000

1) Run karaf
2) Enable the below features
feature:install odl-openflowplugin-flow-services
feature:install odl-dlux-all
feature:install odl-l2switch-all
feature:install odl-l2switch-switch-ui
feature:install odl-l2switch-switch-rest

3) Using mininet connect 2 switches in linear topology with 1000 hosts on each.
4) Now make the below REST CALL to get the nodes.
http://10.11.200.254:8181/restconf/operational/opendaylight-inventory:nodes
5) Controller console is unresponsive for few minutes.
5) After it is responsive the REST provides incorrect data. Below is a script output. Negative values mean the call failed failed to fetch required data.

Time taken for nodes call is 0 milliseconds
Total device Count = 2 (This is correct)
--------------------
Time taken for links call is 0 milliseconds
Total links = -2 (Expecting 2). None found.
--------------------
Time taken for ports call is 0 milliseconds
Total ports = -1 (Expecting 2002)
--------------------
Time taken for host call is 0 milliseconds
Total hosts = 0 (this is fine)
