Can you try the latest version 0.6.1? There was a bug in 0.6.0 which occurs when you have multiple hostnames and you are using a gremlin (JanusGraph) server.

Hi Krishna, are you sure you are using the right configuration? Your log suggests that you are using “127.0.0.1” as your hostname.

What JanusGraph version do you use? Recent TinkerPop versions use Order.asc instead of Order.incr.

Re: JanusGraph database cache on distributed setup
Thanks Marc for making it clear.
@Wasantha, how did you implement your void invalidate(StaticBuffer key, List<CachableStaticBuffer> entries) method? Make sure you evict this key from your Redis cache.
