Not able to run ls -ltr
Hi ,

Whenever i try to execute ls with l as an option the system hangs.

The workload on server is not more than 1.
What could be the reason .

Normal ls works fine but ls -l causes the system to hang.




This is happening when i m in /usr/local/sbin directory.


I can see that the output is getting generated after 3-4 minutes.

See the comparison.
Code:
#time ls
real    0m0.004s
user    0m0.000s
sys     0m0.002s
#time ls -ltr
real    3m2.443s
user    0m0.003s
sys     0m0.002s

Code:
# which ls
alias ls='ls --color=tty'
        /bin/ls

Distribution details
Code:
# lsb_release -a
LSB Version:    :core-3.1-ia32:core-3.1-noarch:graphics-3.1-ia32:graphics-3.1-noarch
Distributor ID: EnterpriseEnterpriseServer

enable(1)							   User Commands							 enable(1)

NAME

       enable, disable - enable/disable LP printers

SYNOPSIS

       /usr/bin/enable printer...

       /usr/bin/disable [-c | -W]  [ -r [reason]] printer...

DESCRIPTION

       The  enable  command  activates	printers,  enabling  them to print requests submitted by the lp command. enable must be run on the printer
       server.

       The disable command deactivates printers, disabling them from printing requests submitted by the lp command. By default, any requests  that
       are  currently  printing  on printer will be reprinted in their entirety either on printer or another member of the same class of printers.
       The disable command must be run on the print server.

       Use lpstat -p to check the status of printers.

       enable and disable only effect queueing on the print server's spooling system. Executing these commands from a client system will  have	no
       effect on the server.

OPTIONS

       The following options are supported for use with disable:

       -c	       Cancels	any requests that are currently printing on printer. This option cannot be used with the -W option. If the printer
		       is remote, the -c option will be silently ignored.

       -W	       Waits until the request currently being printed is finished before disabling printer. This option cannot be used  with  the
		       -c option. If the printer is remote, the -W option will be silently ignored.

       -r [reason]     Assigns	a  reason  for	the  disabling	of  the  printer(s). This reason applies to all printers specified. This reason is
		       reported by lpstat -p. Enclose reason in quotes if it contains blanks. The default  reason  is  "unknown  reason"  for  the
		       existing printer, and "new printer" for a printer added to the system but not yet enabled.

OPERANDS

       The following operand is supported for both enable and disable:

       printer	       The  name of the printer to be enabled or disabled. Specify printer using atomic name. See printers.conf(4) for information
		       regarding the naming conventions for atomic names.

EXIT STATUS

       The following exit values are returned:

       0	       Successful completion.

       non-zero        An error occurred.

FILES

       /var/spool/lp/*	       LP print queue.
