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....
