I am using gdb to examine a core file but the output contains only the method addresses in hex.
Is there anyway to translate these addresses to a human-readable form? :confused: (0 Replies)
I am trying to print a stack trace programatically using backtrace and backtrace_symbols.
The problem is that the stack being printed in a mangled format. Is there a way to get the output in more of a human readable form?

Hi all,
One of our programs written in Java, produced this logfile. This job runs 48 threads and only one thread failed with this error. The code is a blackbox(external product), so cant look at the source code. From what I can infer from the log, the job was trying to write the log messages into... (9 Replies)
I'm on solaris 8. I need to check the stack trace inside my C program. I don't have printstack or walkstack. I tested getcontext and it works. But how do I get the symbols from "stack_t" ? Help please. Many thanks! (4 Replies)

Hi All,
I am trying to debug my core file using kdb.
When I try to get the stack trace I am facing this error.

Hi All
Thought it would be kind of fun to implement a stack trace for a shell script that calls functions within a sub shell. This is for bash under Linux and probably not portable -
#! /bin/bash
error_exit()

echo $1

I have a C program which is running as daemon and has some threads.
The program is running on dual core cpu and it may happen that different threads may run on different cpu core.
The problem is sometimes it crashes with some heap memory corruption probably between threads.

I want the developers to get a mail with Java stack traces on a daily bases. When something is flaged as known issue and will get a fix but mean while this does not need to get sent each dayl. This is what I got so far. It's a bash script that runs some AWK in it.

vtf2profile
VTF2PROFILE(1) Tools VTF2PROFILE(1)NAME
vtf2profile - Generate a TAU profile set from a vampir trace file
SYNOPSIS
vtf2profile [-p profile] [-i interval_start interval_end] [-c] [-h] {-f tracefile}
DESCRIPTION
vtf2profile is created when TAU is configured with the -vtf=<vtf_dir> option. This tool converts a VTF trace file (*.vpt) to a tau profile
set (profile.A.B.C where A, B and C are the node, context and thread numbers respectively).
The vtf file to be read is specified in the command line by the -f flag followed by the file's location. The VTF tracefile specified may be
in gzipped form, eg app.vpt.gz. -p is similarly used to specify the relative path to the directory where the profile files should be
stored. If no output directory is specified the current directory will be used. A contiguous interval within the vtf file may be selected
for conversion by using the -i flag followed by two integers, representing the timestamp of the start and end of the desired interval
respectively. The entire vtf file is converted if no interval is given.
OPTIONS -f tracefile -Specify the Vampir tracefile to be converted.
-p profile -Specify the location where the profile file(s) should be written.
-i interval_start interval_end -Limit the profile produced to the specified interval within the vampir trace file.
-c -Opens a command line interface for the program.
-h -Displays a help message.
EXAMPLES
To convert a vampir tracefile, trace.vpt, to an equivalent TAU profile, use the following:
vtf2profile -f trace.vpt
To produce a TAU profile in the ./profiles directory representing only the events from the start of the tracefile to timestamp 6000, use:
vtf2profile -f trace.vpt -p ./profiles -i 0 6000
