Subject [jira] Created: (GERONIMO-1128) Derby Log Viewer performance problem

Derby Log Viewer performance problem
------------------------------------

         Key: GERONIMO-1128
         URL: http://issues.apache.org/jira/browse/GERONIMO-1128
     Project: Geronimo
        Type: Bug
  Components: console  
    Versions: 1.0    
 Environment: Win32 w/ latest 1.4.2 JDK
    Reporter: Donald Woods


When the Derby Log Viewer is rendered on the Servers Log page, the DerbyLogHelper.java copying
ALL lines from derby.log and sending it back as a request attribute.  As the Derby logfile
grows, this will consume more server cycles and eventually impact other user apps and response
time.

Also, the BufferedReader/FileReader is never closed, so this will leak a file handle everytime
the page is rendered.

This portlet needs to be replaced with the logmanager/LogViewerPortet implementation, so users
can choose how many lines to display....
