Problem summary

****************************************************************
* USERS AFFECTED:  All users of WebSphere Application Server   *
*                  V6.1.0 for z/OS that leverage servlet       *
*                  caching and the Edge Side Include protocol. *
****************************************************************
* PROBLEM DESCRIPTION: Edge Side Include (ESI)                 *
*                      cache statistics and processes not      *
*                      showing up on the cache monitor         *
*                      EdgeStatistics panel.                   *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
Under stress, WebSphere DynaCache does not communicate cache
statistics and other control information correctly with the ESI
surrogate server. The ESI surrogate can be an IBM HTTP server
(IHS) with the WebSphere plugin or the WebSphere Proxy Server.
When a problem occurs, the connection between IHS and WebSphere
Dynacache is broken and  the CacheMonitor application
does NOT show any ESI edge statistics.

Problem conclusion

The communication channel between the ESI surrogate server and
the WebSphere Application Server on zOS has been made
more robust. The connection will now stay up, until the
application server or the ESI surrogate server is stopped.

APAR PK70576 is currently targeted for inclusion in
Service Level (Fix Pack) 6.1.0.25 of the WebSphere
Application Server V6.1 for z/OS.
