There is a failure here, a TikaException meaning that something failed to parse or something. We serialize that failure over the wire to the transport client, but then it fails to deserialize because the Tika jars are probably not in the client classpath...., so you get a generic failure saying "something failed" On Mon, Mar 26, 2012 at 10:38 PM, Shane Witbeck [shane@digitalsanctum.com](mailto:shane@digitalsanctum.com)wrote: > Getting the following when perhaps there is low available memory: > > [ES ClassNotFoundException and others when low memory · GitHub](https://gist.github.com/2209474) ---

Sure enough! As soon as I added the Tika jars to the client I got a more usable exception: > Thanks again kimchy, Shane On Tuesday, March 27, 2012 1:35:50 PM UTC-4, kimchy wrote: > There is a failure here, a TikaException meaning that something failed to > parse or something.
