: I get sometimes (not often): : SolrException e where e.code() == : SolrException.ErrorCode.SERVICE_UNAVAILABLE.code
Are there any errors in your solr server logs? Are you using the DistributedUpdateProcessor (ie: SolrCloud) ? There aren't many places in Solr that will throw a 503 status code, if i had to guess i would suspect that your problem is you are committing too often relative to the amount of warming you are doing, and exceeding the max number of open searchers... https://wiki.apache.org/solr/FAQ#What_does_.22exceeded_limit_of_maxWarmingSearchers.3DX.22_mean.3F : When I catch this exception, I try to commit again, the call doesn't throw, : but the docs are not committed. Am I supposed to add docs again before Hmmm... that is odd, i think we'd definitely need to see the logs from one of these errors (and the lines leading up to it) to understand what might be happening. -Hoss
