Normally, people, are running it with some verbosity options.

Please, explain:
1. what you are willing to do;
2. which example config file was taken as initial;

My feeling, that you missed some example files.

Adding the -v switch produces the following output:

found form_str 
ws_name=PlayEvent&ws_action=Create&descriptor-media_id=%s&credentials-session_id=%s&credentials-consumer_id=%s&credentials-device_id=%s&descriptor-consumer_id=%s&descriptor-media_kind=track&descriptor-device_id=%s&timestamp=1&descriptor-playing_source_type=stream&descriptor-complete_play=1&descriptor-duration=0

The configuration has been post-validated successfully.

I am trying to run a simple POST request which has 6 variables that need 
to be replaced from the input file.


> 2. which example config file was taken as initial;

I used post-form-tokens-fr-file.conf and random_file_records.conf as 
examples. (I tried doing the configuration without the random and with 
and it didn't help). The simplest form of the configuration i tried 
which is exactly like post-form-tokens-fr-file.conf except with 
different data and different post string is:

URL=http://localhost/load/main.php
URL_SHORT_NAME="play-event"
REQUEST_TYPE=POST
FORM_USAGE_TYPE= RECORDS_FROM_FILE
FORM_STRING= 
ws_name=PlayEvent&ws_action=Create&descriptor-media_id=%s&credentials-session_id=%s&credentials-consumer_id=%s&credentials-device_id=%s&descriptor-consumer_id=%s&descriptor-media_kind=track&descriptor-device_id=%s&timestamp=1&descriptor-playing_source_type=stream&descriptor-complete_play=1&descriptor-duration=0
FORM_RECORDS_FILE= ./conf/streamMedia.input
TIMER_URL_COMPLETION = 5000
TIMER_AFTER_URL_SLEEP = 2000

Could it be that there is some limitation on the length of the post 
string that i am exceeding? (My string is a bit long) Or maybe the 
length of each individual data input value?

Thanks,
Brocha

Got it.

Good.

Please, pay attention, that you cannot make a POST without getting
the form, therefore, the first is GET as in the example is required:

# GET-part
URL= http://10.30.6.42:8888/vax/root/Admin
URL_SHORT_NAME="Login-GET"
REQUEST_TYPE=GET
TIMER_URL_COMPLETION = 4000
TIMER_AFTER_URL_SLEEP =0

# POST-part
URL=""
URL_SHORT_NAME="Login-POST"
URL_USE_CURRENT= 1
REQUEST_TYPE=POST
FORM_USAGE_TYPE= RECORDS_FROM_FILE
FORM_STRING= username=%s&password=%s     #means credentials from file
FORM_RECORDS_FILE= ./conf-examples/credentials.cred # Path relative to
curl-loader location

It might be the case, however:

1. Please, make the first Get;
2. Make a capture using some sniffer like wireshark and see in the capture,
   if you are getting the POST-form by Get and that it contains all the
required fields to add.

   You might be consulted at this point by somebody with experience in HTTP,
HTML, etc.

3. Start with 2-3 initial parameters, you may not receive OK, but some
response you may get.
