Script Hangs!
Hi,
I have script which is based on TCL and expect. It is written to test my code. It usually runs fine for a while and hangs after sometime.


Code snippet

set l_temp_timeout $timeout
OUTPUT_LOG2 2 >>>$expect_out(buffer)<<<
OUTPUT_LOG2 2 "Expecting...$my_prompt"
set timeout 3

expect {
$my_prompt { set l 1 }
timeout { OUTPUT_LOG2 2 $expect_out(buffer) }
}
OUTPUT_LOG2 2 "...Out of Expect $my_prompt"



My log for this code normally looks like

Retrying...
>>>^M^M
238114.0^M
^Mswitch(config-if-hsrp)#<<<
Expecting...#
...Out of Expect #



But once this hangs, it looks like


Retrying...
>>>^M^M
704802.0^M
^Mswitch(config-if-hsrp)#<<<
Expecting...#


Screen shot for this

^Mswitch(config-if-hsrp)# echo 704802.0^M
704802.0
^Mswitch(config-if-hsrp)# sh ip route vrf all^M
sh ip route vrf all

IP Route Table for VRF "default"
:

IP Route Table for VRF "cisco3"
'*' denotes best ucast next-hop '**' denotes best mcast next-hop
'[x/y]' denotes [preference/metric]

0.0.0.0/32, 1 ucast next-hops, 0 mcast next-hops
*via Null0, [220/0], 00:25:03, local, discard
255.255.255.255/32, 1 ucast next-hops, 0 mcast next-hops
*via sup-eth1, [0/0], 00:25:03, local



Even I noticed that the prompt did not come back. Not sure whats the problem. Even if the prompt which is "#" did not show up, at least it should have timed out.

Why is it hanging ?

Can you please help ?

Thanks
Naveen

GOOGLE-SITEMAPGEN(1)					      General Commands Manual					      GOOGLE-SITEMAPGEN(1)

NAME

       google-sitemapgen -- simple script to automate production of sitemaps for a webserver

SYNOPSIS

       google-sitemapgen [--testing]  [--help]	[--config=config.xml]

DESCRIPTION

       This manual page documents briefly the google-sitemapgen command.

       This manual page was written for the Debian distribution because the original program does not have a manual page.

       google-sitemapgen  is  a  program that automatically produces sitemaps for a webserver, in the Google Sitemap Protocol (GSP). Sitemap files
       are XML listings of content you make available on your web server. The files can be directly submitted to search engines as hints  for  the
       search  engine  web  crawlers as they index your web site. This can result in better coverage of your web content in search engine indices,
       and less of your bandwidth spent doing it.

OPTIONS

       --config=config.xml
		 Specify the location of the configuration config.xml

       --testing Used to test the sitemap generator configuration.

       --help	 Display a summary of options and exit.
