Failed to determine Thread Name

Hi,

ElasticSearch has been working great when all of a sudden today; I started
seeing these exceptions in my client logs:

[#|2012-05-16T11:20:38.287-0400|INFO|glassfish3.1.2|javax.enterprise.system.std.com.sun.enterprise.server.logging|_ThreadID=90;_ThreadName=Thread-2;|16

Should I be alarmed? I'm not sure how to react...

Thats strange..., its coming from netty library, for some reason the thread
renaming logic there is null... . Which version of ES are you using (so I
will know which netty lib to check).

Shay,

I"m using Elasticsearch 0.19.2.

Thanks for your help.

It seems like getting the current thread in the netty code returned null..,
you can safely ignore this failure, btw, nothing bad will happen from it,
though it is strange that the current thread returned is null..., which JVM
version are you using?
