This seems to be a larger problem or I'm not clear on AMI usage.  I have
tried using the web interface to accomplish this and am running into the
same problem (iax.conf grows at every iteration).

Here's what I'm doing:
http://localhost:8088/asterisk/rawman?action=login&username=foo&secret=bar

and then:
http://localhost:8088/asterisk/rawman?action=updateconfig&reload=no&srcfilename=iax.conf&dstfilename=iax.tmp.conf&Action-000000=newcat&Cat-000000=asdf&Var-000000=&Value-000000=

(following the formula given in the O'Reilly text)

Notice srcfilename is iax.conf and dstfilename is iax.tmp.conf
I attempt to create a new category 'newcat'.  Every time I run this
process iax.conf increases in size by ~ a factor of 2--the contents of
iax.conf are being appended to itself every time.
