Subject RE: Invalid version (expected 2, but 60) or the data in not in 'javabin'
Date Wed, 26 Dec 2012 09:42:59 GMT
Thanks for the prompt reply Mark.

Just to give you some background, I'm simulating a multi-shard environment by running more
than 200 Solr Cores on a single machine (machine does not seem to be stressed) and I'm running
a distributed facet.
The Solr server is running trunk 1404975 with SOLR-2894 patch applied over it (the one from
Nov. 12th).
While I'm running the distributed request, other clients are sending various search requests
to the Solr server.
This issue is randomly happening and does not reproduce constantly.
As I wrote earlier, I applied the Debugging.patch from SOLR-3258 to see the actual response
and noticed that an actual XML reply was received and the XML itself was corrupt (as if a
chunk of text was taken out right from the middle of it).

Since this reproduces randomly, the only thing that comes to mind is some kind of concurrency
related problem.

Any help would be greatly appreciated,

The problem is not necessary xml - it seems to be anything that is not valid javabin - I've
just most often seen it with 404s that return an html error.

I'm not sure if there is a jira issue or not, but this type of thing should be failing in
a more user friendly way.

As to why your response is corrupt, I have no guesses.

This is easily repeatable? It's happening every time, or randomly?

I also noticed that the response is corrupt (i.e. as if a chunk of text has been taken out
of the middle of the reply - some kind of overrun perhaps?).
