3.2.2 Collecting Fatal Error Log Information
When a Java application aborts, the fatal error log file (hs_err_pid<pid>.log) is generated.
The contents of this file vary depending on the architecture and the Java version. (For example,
early Java versions generate less information in the fatal error log.). Following is a summary of
the type of information contained in this file:
1. The error causing the Java VM to abort, including the pc, process id, and thread id at which
the error occurred. For example:
# An unexpected error has been detected by HotSpot Virtual Machine:
#
# SIGSEGV (11) at pc=7541df20, pid=25675, tid=1
2. The Java version and problematic frame. For example:
# Java VM: Java HotSpot(TM) Server VM (1.4.2
# 1.4.2.10-060112-19:42-IA64N IA64 mixed mode)
# Problematic frame:
# j spin.main([Ljava/lang/String;)V+5
3. Information about the current thread, including:
a. Executing thread
b. siginfo at the point of failure
c. Stack pointer and hex dump of the top of memory stack
d. Hex dump at the location of the current pc
e. Stack range and stack free space
4. Process information, including:
a. Dump of all active threads at the time of the abort (SDK 1.4.2.04+)
b. Java VM state (whether at safepoint or not) (SDK 1.4.2.10+)
c. mutex state (SDK 1.4.2.10+)
d. Summary of heap status; for example:
Heap

eden space 5056K, 2% used [6d400000, 6d424040, 6d8f0000)

the space 16384K, 6% used [71400000, 71517860, 71517a00, 72400000)
e. dynamic libraries loaded by the process (SDK 1.4.2.04+)
f. Java VM arguments (SDK 1.4.2.04+)
g. Java-related environment variables
5. System Information. This includes operating system name, version, processor, memory, and
system load. For example:
OS: HPUX
uname:HP-UX B.11.23 U ia64
rlimit: STACK 98252k, CORE 2097151k, NOFILE 4096, AS infinity
