本文详细记录了一次 Resin 服务器出现 500 ServletException 的错误排查过程，并提供了具体的解决方案。当遇到 com.caucho.db.block.Block.validateIsIndex 抛出 java.lang.IllegalStateException 异常时，可以通过删除 resin-data 目录来重置服务器状态。

解决办法：


 
 
  
  resin-data
  
  

  
  

  
  The resin-data directory contains Resin's internal data, including deployed webapps, the health system data, and distributed caches.
  
  

  
  

  
  If Resin's internal data becomes corrupted, you can remove the resin-data directory to reset the state. If you have multiple servers in a triad hub, the reset server will restore its values from the other servers.
  
  

  
  

  
  When Resin is deployed in a Unix environment, the resin-data will typically be in /var/resin/resin-data.
