Hi Peter, there is a tool from sun (they use it in glassfish) to check which class/method opened which open file handles. Not sure if it will help with several open file handles; but can you try to check this out with your use-case?
http://blogs.sun.com/quinn/entry/tool_for_diagnosing_failed_glassfish the tool should also work with tomcat (at least I got it to run with tomcat when I had to). regards, Martin On 6/21/07, Scott O'Bryan <[EMAIL PROTECTED]> wrote:
I saw this as well using Oracle JDeveloper so I agree that I don't think this is a Tomcat issue. I'm not sure what might be causing this though because I shut down my webserver and restarted it and everything has been working fine since. What happens when you restart tomcat?
