APAR status
Closed as program error.

Error description
The application server that is currently marked down by
the plug-in is retried immediately before the expiry of
the retry interval.
-
This happens when using a combination of the plug-in
config options RetryInterval and ServerIOTimeout.
Local fix Problem summary
****************************************************************
* USERS AFFECTED: All users of web server plug-ins for         *
*                 WebSphere Application Server version 5 and   *
*                 6.                                           *
****************************************************************
* PROBLEM DESCRIPTION: The web server plug-in retries the      *
*                      application server too soon,            *
*                      if the plug-in config option            *
*                      "SeverIOTimeout" is set greater than    *
*                      or equal to the value of the plug-in    *
*                      config option "retryInterval".          *
*                                                              *
*                      In such a case, the web server          *
*                      plug-in retries the application         *
*                      server immediately after                *
*                      discovering that application server     *
*                      has gone down before the                *
*                      "retryInterval" has expired.            *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
The web server plug-in was using the time at which the request
arrived and the last time a request failed to the application
server to decide whether retryInterval has expired.

This logic is changed to use the current time and the
last time at which a request failed to the application server
to decide whether retryInterval has expired.
Problem conclusion
The web server plug-in is enhanced so that application
server retry logic works correctly and the application
server is retried only after the retryInterval has expired.

The fix for this APAR is currently targeted for inclusion
in cumulative fix 5.1.1.13 and fixpacks 6.0.2.17 and 6.1.0.5.
