| Re: [smila-dev] Zookeeper fatal error and SMILA shutdown |
Hi Peter, never saw something like that with zookeeper before. (NoClassDefFoundError ???) Are you doing something special in that branch? Is it possible that the main error happened before and this was a subsequent error? Best Regards, Andreas Von: smila-dev-bounces@xxxxxxxxxxx [mailto:smila-dev-bounces@xxxxxxxxxxx] Im Auftrag von Peter Wissel Hi folks, lately I was wondering why my SMILA instance doesn’t answer anymore. When I took a look in log file I found this exceptions followed by a graceful shutdown of the framework: 2012-10-21 00:57:27,873 WARN [NIOServerCxn.Factory:0.0.0.0/0.0.0.0:2181 ] server.NIOServerCnxn -

I’m using the branch “2012-01-27_r2218_v1.1-prep” in SMILA SVN. Thanks you. Best regards Peter |
