Thanks for sharing the log file. I will look into the attachment file for further analysis. It will be more helpful If you reproduce the same by setting the log TRACE for the elan bundle.

Please execute the below command under Karaf prompt

set TRACE org.opendaylight.netvirt.elan

and reproduce the issue and share the logs. It will be more helpful in fixing the problem.
