In UNIX environments the error ‘Too many open files’ in the Alfresco log files is often associated with Lucene. The issue manifests itself on UNIX systems where often the system is configured by default to allow users a maximum of only 1024 open file handles, which is often not sufficient for the file structure used by the indexes.
在UNIX环境中，Alfresco日志文件中的错误“打开的文件太多”通常与Lucene相关。该问题在UNIX系统上表现出来，通常系统默认配置为允许用户最多只有1024个打开的文件句柄，这对于索引所使用的文件结构通常是不够的。
Although Lucene 2.0 suffers less from this problem, errors may still occur on systems during periods of heavy use and therefore it is recommended that on production Alfresco systems the normal file handle limit is increased.
尽管Lucene 2.0受此问题的影响较小，但在大量使用期间，系统上仍可能发生错误，因此建议在Alfresco生产系统上增加正常文件句柄限制。
