Problem summary

• ****************************************************************
  USERS AFFECTED:
  WebSphere MQ WCF, XMS and .net application users using the
  managed .net client.
  
  
  Platforms affected:
  Windows
  
  ****************************************************************
  PROBLEM SUMMARY:
  The WebSphereMQ .Net managed client maintains a connection
  pool to allow connections to queue managers already in use to be
  established quickly. However there were errors in the locking
  code used when connections were added or removed to the pool and
  in handling connection errors.
  

Problem conclusion

• Connection pool locking mechanisms and use were corrected.
