IT30963: BIPBROKER CAN BECOME UNRESPONSIVE OR EXTREMELY SLOW AFTER CONVERTER CACHE CORRUPTION

APAR status

• Closed as program error.

Error description

• The bipbroker process can become unresponsive despite consuming
  100% CPU, or take unreasonably long amounts of time to perform
  a deploy manager cache refresh if a converter cache corruption
  event occurs.
  
  The converter cache has been re-written from the
  ground up to avoid such cache corruption events.

Problem summary

• ****************************************************************
  USERS AFFECTED:
  All users of IBM Integration Bus v10 and App Connect Enterprise
  v11
  
  
  Platforms affected:
  MultiPlatform, z/OS
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  The product uses a number of converters to convert text between
  different encoding formats, such as UTF-8 and UTF-16. These
  converters are cached on a per-thread basis for performance.
  This cache can become corrupted in the bipbroker process which
  can cause it to become unresponsive despite consuming 100% CPU,
  or take unreasonably long amounts of time to refresh its
  internal cache of all the currently deployed and configured
  state, or can cause abends.
  

Problem conclusion

• The converter cache has been re-written to improve performance
  and reduce the possibility of cache corruption occuring.
