Error description

When the number of Servants is set such that the minimum
number of servants is set to less than the maximum the
partner logs may grow until they become full.
For example:
BBOM0001I      wlm_maximumSRCount: 8.
BBOM0001I      wlm_minimumSRCount: 1.
This occurs when a Servant is stopped and peer recovery
processing is undertaken for the Servant   Peer recovery
successfully recovers all the XA resources associated with
the stopped servant, and this is recorded at the the control
region.  However, during control region shutdown processing,
recovery processing interprets the fact that the XA
resources have recovered as meaning that there is nothing
required for recovery from the partnerlogs at the next server
startup, and resets the recovery epoch (a number that defines
the scope of resources to be recovered) - this causes resource
references to be left in the partner log, potentially never
removed.

The following error is seen in the Servant log when the
log fill full conditon occurs:

Problem summary

****************************************************************
* USERS AFFECTED:  All users of IBM WebSphere Application      *
*                  Server V8.0 and V8.5                        *
****************************************************************
* PROBLEM DESCRIPTION: XA partner log is marked as failed      *
*                      due to the recovery log service being   *
*                      unable to add a partner entry to the    *
*                      filled log.                             *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
With a specific RACF authorization, a server shutdown will
reset the RRS Resource Manager token, which includes setting
the recovery epoch value to zero.  If XA resources had been
logged to the XA partner log during the lifecycle of the
server before the shutdown, these resources will not have yet
been recovered, and will remain in the log until recovery on
them has been completed.  However, due to the resetting of the
epoch value, these resources will potentially remain hidden
from recovery, resulting in the partnerlog gradually filling
over time, eventually causing the server to fail during server
startup.

Problem conclusion

Ensure that the resource manager token is not reset if there
are XA resources that are currently unrecovered.
