Problem summary

•  USERS AFFECTED: Tivoli System Automation for
  Multiplatforms user's using GDPS Multiplatform Resiliency for
  System z for management of Linux on z/VM guests (xDR z/VM guest
  Linux on System z)
  *****************************
  In environments with a large number of z/VM guests e.g. more
  than 150 guests on one z/VM system, the default buffer size
  for the command 'vmcp' can be too small for the output of the
  CP command 'q signals'

•  The xDR proxy code has been updated with
  code to handle cases, where the default buffer size for vmcp
  is too small for the output returned
  The official fix is included in Tivoli System Automation for
  Multiplatforms 4.1 fix pack 4
