Checking System Crash Dumps
Sun provide (although not officially supported) a tool called iscda for analysing dumps produced when a system crashes. The script uses adb to produces a readable report from the dumps produced. By reading through this report, it should become clear what caused the crash.
To use the script do the following:
Copy the csript to the directory containing the vmcore and unix files e.g. /var/crash
run the script as follows: ./iscda unix.# vmcore.# > /tmp/iscda.output
Check through the iscda.output report
You can also run it against a live system as follows:
./iscda /dev/ksyms /dev/mem > /tmp/iscda.output
