Hello,
We sometimes see the error below in our `master` when indexing. Our master is
currently the node we send documents to - we've not yet implemented
CloudSolrServer in Apache Nutch. This causes the indexer to crash when using
Nutch locally, the task is retried when running on Hadoop. We're running it
locally in this test set up so there's only one indexing thread.
Anyway, for me it's quite a cryptic error because i don't know what connection
has timed out, i assume a connection from the indexing node to some other node
in the cluster when it passes a document to the correct leader? Each node of
the 10 node cluster has the same configuration, Tomcat is configured with
maxThreads=512 and a time out of one second.
We're using today's trunk in this test set up and we cannot reliably reproduce
the error. We've seen the error before so it's not a very recent issue. No
errors are found in the other node's logs.

Any thoughts to share? Is this a bug? A misconfiguration?
Thanks,
