Solaris 2.x Core Dump Analysis
If you are having trouble getting a core dump, see the savecore page.
Several useful pieces of information can be found by running
strings on the
vmcore.# file and piping it through
strings vmcore.# | more.
In particular, this will tell you the architecture of the system and the
OS level. The message buffer is also near the top of the
strings output, and may include messages that had not been
written to the console or log files yet. (Note that the message
buffer is a ring buffer, so the messages may not be in cronological order.)
If the system panic'ed due to a bad trap,
adb can determine the instruction that was running at the
time of the crash.
crash can also provide useful
information, including lock and kernel memory allocation.
output is notably less cryptic than
commands are also available for crash dumps.
After running the command on the corefiles (eg
netstat -d unix.#
vmcore.#), compare the output to that on the live system, since
some of the options do not report the crash dump statistics.
