Subject RE: [Solr4 beta] error 503 on commit
Date Fri, 07 Sep 2012 21:57:15 GMT
Hi,

We've seen this too on one of the test nodes yesterday, it ran on a build of a few days old.
The node receiving documents complained it could not forward them to the fifth node and returned
a 503. The fifth node itself only logged a NPE and the 503, nothing more, no stack traces.

There was no heavy committing going on (we only use auto commit of a few seconds) and it were
only about 500 documents. The first two batches were accepted but then it died. It failed
very consistently. Perhaps it accepted the first batches because no document was sent to the
shard leader on that node yet.

Restarting the node fixed the trouble.
