Race condition encountered: attempted to load session[SESSION_ID] which has been created but not yet serialized.

[asundaram]

We are getting this error in Production while using Tomcat 6 version of the redis session manager. Since saveOnChange feature doesn't exist in this branch, we cannot use it (unfortunate). We would like to know what impact this exception has to the users.

In New Relic we see transactions with these errors have a 200 HTTP response code. Does this mean that the user did not receive errors(maybe because of a retry somewhere)? Also there are 100's of such errors everyday in our logs but haven't heard any issues reported from our users or testers.

Please advice.

@haroldyong , can you please provide with an example, how did solve this.

Also appreciate if you can elaborate on MSM JAR(s) - kryo-serializer, javolution-serializer, xstream-serializer or any other.

Thanks
