OA40432: HUB CRASH DURING FTO UPGRADE

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• PROBLEM DESCRIPTION:
  
  The HUB crashes eventually during the upgrade process while the
  HUB and
  MIRROR are at different versions. This is specifically known to
  occur
  while one HUB is at 6.23 while the other has been upgraded to
  6.23 FP1.
  
  
  RECREATE INSTRUCTIONS:
  
  Have both HUBs at 6.23 base level. Upgrade one of the HUBs and
  start it.
  There may be a specific order the HUBs need to be upgraded for
  this
  problem to occur, so it is conceivable that some upgrades like
  this may
  not fail.
  

Local fix

• Do not connect the two HUBs until they are both at the same
  level of
  code.

  * RECOMMENDATION: Apply the PTF.                               *
  ****************************************************************
  The hub monitoring server and mirror monitoring server are
  expected to be installed at the same level at all times.
  However, sometimes these two monitoring servers are at
  different levels during the process of upgrading the two
  servers. There are cases when some level differences between
  the hub monitoring server and mirror monitoring server are
  incompatible. When this happens, a crash can occur at one of
  the two servers if the two servers remain at different
  levels for a sufficient length of time. The time frame is
  generally expected to be a few hours.
  

Problem conclusion

• The code has been changed to eliminate the memory growth
  that leads to the crash. It is still recommended that the
  level difference be kept to a small a time period as
  possible.
