We have an AIX5.3 server with application which is written in C. We are facing server (lpar) hangs intermediately. If we open new telnet window prompts for user and takes hell of a time to authenticate, not only that if we run ps -aef then also it takes lot of time.
Authentication usually involves a third machine - DNS server, LDAP server, etc.. It is possible that this problem lies there.

surprisingly there is no cpu bottleneck as cpu is almost 80% idle, there is o memory or paging, there are no errors on network card. The only thing we observed is there were so many errors of core dump for the application.
Have you tried to analyze these cores? Install the fileset "bos.adt.debug" and use "dbx" to analyze the core.
I hope this helps.

NAME
page_util_quote - page character quoting utilities
SYNOPSIS
package require page::util::quote ?0.1?
package require snit
::page::util::quote::unquote char
::page::util::quote::quote'tcl char
::page::util::quote::quote'tclstr char
::page::util::quote::quote'tclcom char
_________________________________________________________________
DESCRIPTION
This package provides a few utility commands to convert characters into various forms.
API
::page::util::quote::unquote char
A character, as stored in an abstract syntax tree by a PEG processor (See the packages grammar::peg::interpreter, grammar::me, and
their relations), i.e. in some quoted form, is converted into the equivalent Tcl character. The character is returned as the result
of the command.
::page::util::quote::quote'tcl char
This command takes a Tcl character (internal representation) and converts it into a string which is accepted by the Tcl parser, will
regenerate the character in question and is 7bit ASCII. The string is returned as the result of this command.
::page::util::quote::quote'tclstr char
This command takes a Tcl character (internal representation) and converts it into a string which is accepted by the Tcl parser and
will generate a human readable representation of the character in question. The string is returned as the result of this command.
The string does not use any unprintable characters. It may use backslash-quoting. High UTF characters are quoted to avoid problems
with the still prevalent ascii terminals. It is assumed that the string will be used in a double-quoted environment.
::page::util::quote::quote'tclcom char
This command takes a Tcl character (internal representation) and converts it into a string which is accepted by the Tcl parser when
used within a Tcl comment. The string is returned as the result of this command.
