When the JavaVM crashes, JavaVM outputs the debug information to the standard output and error report file.

The following are cases when the debug information is output to the error report file:

• When a signal occurs in JNI
• When C heap is insufficient in the JavaVM
• When an unexpected signal occurs in the JavaVM
• When an Internal Error (internal logical error) occurs in the JavaVM

The contents of message log output in the following cases are as follows.

Table 5-26 Message log output by JavaVM

Message type	Output destination
When a signal occurs in JNI or message in JavaVM#	Standard output Error report files
Insufficient C heap message#	Standard output Error report files
Internal Error occurrence message#	Standard output Error report files
Thread creation failure message#	Standard output

The JavaVM proprietary output destination or output contents exist.

Note that the thread creation failure message is output only in the standard output.
