APAR status
Closed as program error.
Error description
WSAS code path in this case is not closing the fileStreams that
are being opened, which is leading to "too many open files"
errors when we have 1,000 messages or more.
Local fix Problem summary
****************************************************************
* USERS AFFECTED: WebSphere Application Server adminconsole *
* users who browse the runtime messages tab. *
* If there are many messages then Application *
* Server starts encountering numerous errors *
****************************************************************
* PROBLEM DESCRIPTION: When a user logs in to the admin *
* console and views the Application *
* Server runtime messages, the system *
* starts encountering numerous errors *
* (too many open files, class not found *
* erros, etc.). The errors are caused *
* by the process limit of 2048 file *
* handles being reached. *
* *
* When the Application Server runtime *
* messages are selected, over 1000 file *
* handles are allocated. The number of *
* file handles seems to be related to the *
* number of error messages. In any *
* case, while the runtime messages view *
* is open, the number of available file *
* handles is greatly depleted *
****************************************************************
* RECOMMENDATION: *
****************************************************************
This occurs because in the File MessageLookup.java , the
files in an entire directory are opened and read but not
closed which finally leads the system to run out of file
resources leading to numerous errors
Problem conclusion
As part of code change the files which are opened and being
read are closed.
The fix for this APAR is currently targeted for inclusion in
fixpack 5.0.2.11 and 5.1.1.4.
