    Many open files jndi.properties by JBoss AS 5 process

      Hi all,

       

      Last time we recieved that our JBoss AS 5 process is openning a lot of jndi.properties files, and not closing it.

       

      This cause that after few hours we are getting in server.log error "To many open files":

       

      2014-04-30 09:38:18,000 ERROR [org.apache.tomcat.util.net.JIoEndpoint] (http-10.126.191.20-8080-Acceptor-0) Socket accept failed

      I know that this problem is connected with limits on linux server. We can of course increase number of opened files by process, but I think that it will only postpone the problem.

       

      On JBoss AS 5 we have got some WebServices which uses Datasources by JNDI.

       

      Could anyone explain why jndi.properties files not closing and how resolve this problem ?
