Error description
Error Message: After a Java dump is triggered, the JVM issues a JVMDUMP032I "JVM requested Java dump" message, followed by a crash and JVM termination. The Java dump produced is truncated. .

The Java application is running a large number of Java threads (typically 4,000 to 5,000).
Local fix
Disable Java dumps using the command line option -Xdump:java:none.
Problem summary
The problem is caused when the JVM is running a large number of Java threads and a Java dump is triggered.
Problem conclusion
The JVM has been updated to prevent the crash from occurring. If the JVM is running a large number of Java threads (typically 4,000 or more), the amount of information collected and written to the Java dump for each thread is reduced by omitting the native stack. . This APAR will be fixed in the following Java Releases: 6 SR16 FP4 (6.0.16.4) 6 R1 SR8 FP4 (6.1.8.4) 7 R1 SR3 (7.1.3.0) 8 SR1 (8.0.1.0) 7 SR9 (7.0.9.0) .
