Is my code in an Infinite Loop?
Production C code compiled without the dash-g option is running, and seems to be in an infinite loop. Is there a way to tell? Is there a diagnostic tool that will report what objects or what lines of code or even what functions are being executed?
Or is my best option to kill it with a dump?
Thanks in advance for any help you can provide.

Hi,
whenever I am giving a 'ls' command system is going into infinite loop displaying the current home directory.
There is no separate shell script/file with ls name anywhere in the system.
I am using Solaris 10.
Any help / guidance in solving this problem is highly appreciated.

Hi guys, I'm having a problem getting my infinite loop to loop.

LVMDUMP(8) System Manager's Manual LVMDUMP(8)
NAME
lvmdump - create lvm2 information dumps for diagnostic purposes
SYNOPSIS
lvmdump [options] [-d directory]
DESCRIPTION
lvmdump is a tool to dump various information concerning LVM2. By default, it creates a tarball suitable for submission along with a prob-
lem report.
The content of the tarball is as follows:
- dmsetup info
- table of currently running processes
- recent entries from /var/log/messages (containing system messages)
- complete lvm configuration and cache
- list of device nodes present under /dev
- if enabled with -m, metadata dump will be also included
- if enabled with -a, debug output of vgscan, pvscan and list of all available volume groups, physical volumes and logical volumes will be
included
- if enabled with -c, cluster status info
OPTIONS
-h -- print help message
-a -- advanced collection
WARNING: if lvm is already hung, then this script may hang as well if -a is used
-m -- gather LVM metadata from the PVs
This option generates a 1:1 dump of the metadata area from all PVs visible to the system, which can cause the dump to increase in
size considerably. However, the metadata dump may represent a valuable diagnostic resource.
-d directory -- dump into a directory instead of tarball
By default, lvmdump will produce a single compressed tarball containing all the information. Using this option, it can be instructed
to only produce the raw dump tree, rooted in directory.
-c -- if clvmd is running, gather cluster data as well
ENVIRONMENT VARIABLES
LVM_BINARY
The LVM2 binary to use. Defaults to "lvm". Sometimes you might need to set this to "/sbin/lvm.static", for example.
DMSETUP_BINARY
The dmsetup binary to use. Defaults to "dmsetup".
