Abstract:  APAR TO REQUEST SDK IFIX - 1.4.1 SR2B + 75855 + 77559 + 76932 +  76883 + 75119 + 79857

Description/symptom of problem:  Customer is running WebSphere 5.1.0.1 with Java fullversion     
 J2RE 1.4.1 IBM Windows 32 build ca1411sr2b-20040520.  Operating 
 system is AIX 5.2.  Customer requires the following defects     
 applied to SR2B:                                                
       75885 fix for intermittent CORBA NO MEMORY errors         
       76932 for Typecode indirection problems                   
       77559 to solve the additional proxy problems              
       76883 for Mismatched Serial version UID                   
       75119 to add -Xp,-Xk functionality                        
       79857 JIT memory leak resolution                          
 The Ifix is required for the AIX and Windows operating system   
 platforms.                                                      
 Customer was experiencing several ORB issues with their         
 application.                                                    
 These issues were resolved by SOV defects 75885, 76932, 77559,  
 and 76883.  Subsequently, the application began to experience   
 out of memory issues resulting from heap fragmentation.  SOV    
 defect 75119 is needed to  add -Xp and _Xk functionality to the 
 JDK.  Finally, a memory leak was detected.  The cause of the    
 leak was traced to a defect in the Just In Time (JIT) compiler. 
 SOV defect 79857 is needed in this Ifix to address the leak.
