Exceptions

[ProTip]

Hello,

I saw a couple of these on both servers in the cluster yesterday. I believe the exception is coming from the Service Stack client though.. I'm running the Ubuntu Precise packaged Redis v2.2.12; not sure if I should go with a newer version?

Description: The process was terminated due to an unhandled exception.
Exception Info: ServiceStack.Redis.RedisResponseException
Stack:
   at ServiceStack.Redis.RedisNativeClient.CreateResponseError(System.String)

   at Harbour.RedisSessionStateStore.RedisSessionStateStoreProvider.GetDistributedLock(ServiceStack.Redis.IRedisClient, System.String)

Is the middle one the real exception? It looks like ServiceStack.Redis.RedisResponseException is attempting to be serialized. You're most likely going to have to take this up with ServiceStack because there isn't much I do with it. FYI - I'll be upgrading to StackExchange.Redis for v2, so it should hopefully be more stable.
