Does anyone know what would cause the following error?: 10:45:10 AM org.apache.solr.handler.SnapPuller copyAFile
SEVERE: *Unable to move index file* from: /home/solr/cores/core8/index.20100119103919/_6qv.fnm to: /home/solr/cores/core8/index/_6qv.fnm This occurred a few days back and we noticed that several full copies of the index were subsequently pulled from the master to the slave, effectively evicting our live index from RAM (the linux os cache), and killing our query performance due to disk io contention. Has anyone experienced this behavior recently? I found an old thread about this error from early 2009, but it looks like it was patched almost a year ago: http://old.nabble.com/%22Unable-to-move-index-file%22-error-during-replication-td21157722.html Additional Relevant information: -We are using the Solr 1.4 official release + a field collapsing patch from mid December (which I believe should only affect query side, not indexing / replication). -Our Replication PollInterval for slaves checking the master is very small (15 seconds) -We have a multi-box distributed search with each box possessing multiple cores -We issue a manual (rolling) optimize across the cores on the master once a day (occurred ~ 1-2 hours before the above timeline) -maxWarmingSearchers is set to 1.
