Ovsdb exception when using more than 12 bridges

Have you ever had problems with the following exception when you use the public Node connect(String identifier, Map<ConnectionConstants, String> params) from IConnectionServiceInternal? Strangely enough, this happens only when I start Mininet with 13 or more bridges and the log is gets flooded with this exception.

I tried both mininet 2.1 and 2.2b. I also tried ovsdb 0.5.0-1-SNAPSHOT/ and 0.5.1-SNAPSHOT/. The newer versions have different dependencies and do not integrate in hydrogen.

Is there any solution for it?

credits to Chris O'Shea. Thanks to his suggestion I tried it again and it does work. I am not able to convert his comment to an answer.

Thanks for remind me this, There is a quick work around of changing the buffer size in;a=blob;f=library/src/main/java/org/opendaylight/ovsdb/lib/impl/ increase 100000
