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

Test::Script(3) 					User Contributed Perl Documentation					   Test::Script(3)

NAME
Test::Script - Basic cross-platform tests for scripts DESCRIPTION
The intent of this module is to provide a series of basic tests for 80% of the testing you will need to do for scripts in the script (or bin as is also commonly used) paths of your Perl distribution. Further, it aims to provide this functionality with perfect platform-compatibility, and in a way that is as unobtrusive as possible. That is, if the program works on a platform, then Test::Script should always work on that platform as well. Anything less than 100% is considered unacceptable. In doing so, it is hoped that Test::Script can become a module that you can safely make a dependency of all your modules, without risking that your module won't on some platform because of the dependency. Where a clash exists between wanting more functionality and maintaining platform safety, this module will err on the side of platform safety. FUNCTIONS
script_compiles script_compiles( 'script/foo.pl', 'Main script compiles' ); The "script_compiles" test calls the script with "perl -c script.pl", and checks that it returns without error. The path it should be passed is a relative unix-format script name. This will be localised when running "perl -c" and if the test fails the local name used will be shown in the diagnostic output. Note also that the test will be run with the same perl interpreter that is running the test script (and not with the default system perl). This will also be shown in the diagnostic output on failure. script_runs script_runs( 'script/foo.pl', 'Main script runs' ); The "script_runs" test executes the script with "perl script.pl" and checks that it returns success. The path it should be passed is a relative unix-format script name. This will be localised when running "perl -c" and if the test fails the local name used will be shown in the diagnostic output. The test will be run with the same perl interpreter that is running the test script (and not with the default system perl). This will also be shown in the diagnostic output on failure. SUPPORT
