Java application running on AIX 4.3.3 may terminate unexpectedly if the kernel fileset bos.mp or bos.up are at 4.3.3.77.
Run the command lslpp -l bos.ip bos.mp to determine the kernel fix level.
It is recommended that all Java customers running on AIX 4.3.3 upgrade to 4.3.3.78. A fix is available that will update the kernel to suggested level. You will need to obtain the fix for Authorized Problem Analysis Report (APAR) IY25282.
Installing the fix for IY25282 will correct the Java termination condition. A further fix will be released in the first quarter of 2002 using APAR number IY26149.
Note that AIX 5.1C ships with IY25377, which contains the same fix.
