Hi,
We migrated to Solr 4.3 from 3.5 yesterday. We use multicore Master Slave
architecture and use external scripts to sync the slaves. Every 2-3 hours
cores on our slaves start going down (not all but some. We have about 17
cores). And the logs show the following exception:
1256587 [http-bio-/0.0.0.0-80-exec-2] ERROR
