  ****************************************************************
  In a cluster environment, attributes of a SIP session are
  replicated between application servers in the cluster. Each
  attribute is written to an object stream before delivery to
  the backup container.
  The problem occurs when the code that serializes the attribute
  value throws an exception of type java.lang.Error (or one that
  extends java.lang.Error). The container does not catch such
  exceptions properly, and does not recover from this situation.
  Under specific timing conditions, this failure may cause the
  application server to stop processing future SIP calls.
  

Problem conclusion

• The container now properly handles this situation.
  
  The fix for this APAR is currently targeted for inclusion in
  fix pack 1.0.0.7 for the Feature Pack for Communications
  Enabled Applications. Please refer to the Recommended Updates
