Hi rwb1959,

This matter has become of great urgency to me. I got a new core dump today, and I need to analyze it. I am using dbx, and I see that one element in my array is blank even though it should contain data valid data, and this is the source to our program bombing out.

The question is, using the core and dbx can I get a trace of every time this array was refferenced and/or modified. Do I need a different debugger? If the core isn't enough, is there a different method to get a trace of my program?

Another big problem is that this oly happens on the customer';s machine, I cannot replicate it on my dev machine. And even worse, when I dial in to the customer I cannot reproduce it either?

If you have any suggestions I would greatly appreciate ie.

Thanks,
ebh

jstack(1)						      General Commands Manual							 jstack(1)

NAME
jstack - stack trace SYNOPSIS
jstack [ option ] pid jstack [ option ] executable core jstack [ option ] [server-id@]remote-hostname-or-IP DESCRIPTION
jstack prints Java stack traces of Java threads for a given Java process or core file or a remote debug server. For each Java frame, the full class name, method name, 'bci' (byte code index) and line number, if available, are printed. With the -m option, jstack prints both Java and native frames of all threads along with the 'pc' (program counter). For each native frame, the closest native symbol to 'pc', if available, is printed. C++ mangled names are not demangled. To demangle C++ names, the output of this command may be piped to c++filt. NOTE - This utility is unsupported and may or may not be available in future versions of the J2SE SDK. jstack is not currently available on Windows platforms or on the Linux Itanium platform. PARAMETERS
Options are mutually exclusive. Option, if used, should follow immediately after the command name. pid process id for which the stacktrace is to be printed. The process must be a Java process. To get a list of Java processes running on a machine, jps may be used. executable Java executable from which the core dump was produced. core core file for which the stack trace is to be printed. remote-hostname-or-IP remote debug server's (see jsadebugd) hostname or IP address. server-id optional unique id, if multiple debug servers are running on the same remote host. OPTIONS
-m prints mixed mode (both Java and native C/C++ frames) stack trace. -h Prints a help message. -help Prints a help message. SEE ALSO
pstack(1) c++filt(1) jps(1) jsadebugd(1) KNOWN BUGS
Mixed mode stack trace, the -m option, does not work with the remote debug server. 13 June 2004 jstack(1)
