Answer 1

As explained in this SOLR Jira, you can try the following options:

• increasing your ulimit using: ulimit -n 1000000
• set useCompoundFile to true in solrconfig.xml to use Lucene's compound file format
• use a lower mergeFactor which will result in fewer segments and hence fewer open files.
