Hi, James!
I am not sure what exactly is the problem, but I have an assumption.
When the scenario was failing, where exactly was the $avp(jimmy) first
declared? Inside the LUA script? Is it now first declared in OpenSIPS?
Is there any chance you could reproduce this issue again in full debugging?

I made a few more changes to my code and tested some more and now the
problem has gone away and I can no longer replicate it. Perhaps it is
just something I do not fully understand about AVPs or opensips or the
lua implementation. I was able to reproduce it 100% of the time for
a while, but now can not – strange!
Any thoughts what happened in the original post?

*Subject:* [OpenSIPS-Users] LUA AVP issue?
I am testing the Lua module in hopes of being able to use it more
later, but am coming across some strange things.
Is this the best place to ask about it? If not point me in the right
direction.
AVP_set or AVP_get (in Lua module) seem to be getting data for/from
other AVP(s).
I have included enough code from opensips.cfg and the lua file to be
able to replicate this problem. It happens 100% of the time.
I am using
* opensips 1.8
* CentOS 5.8
* Lua 5.1.4
=============
Opensips.cfg (partial file)
=============
## route[INVITE] is called for all invites – simple way to test J
route[INVITE] {
xlog("In route_INVITE\n");
$avp(abcde) = "bean";
xlog("** ** avp(abcde) = $avp(abcde)\n");
if ( lua_exec("invite") ) { ## call the invite method in lua file
xlog("lua_exec returned TRUE\n");
} else {
xlog("lua_exec returned not true\n");
}
xlog("** ** avp(jimmy) = $avp(jimmy)\n"); ## this avp is
reporting the value set in lua to another avp … WHY?
sl_send_reply("486", "I am not answering now!");
exit;
}
=============
Lua (partial file)
=============
function invite(param)
xlog("********** ---> INVITE test from lua -- getpid =" ..
getpid() .. "\n");
-- AVP_get("jimmy") returns a null because it is not set - this is
expected.
xlog("********** ---> INVITE test from lua -- AVP_get(jimmy) ="
.. tostring(AVP_get("jimmy")) .. "\n");
AVP_set("bingo","Old_mcDonald");
xlog("********** ---> INVITE test from lua -- AVP_get(bingo) ="
.. tostring(AVP_get("bingo")) .. "\n");
xlog("********** ---> INVITE test from lua -- AVP_get(abcde) ="
.. tostring(AVP_get("abcde")) .. "\n");
xlog("********** ---> INVITE test from lua -- AVP_get(fred) =" ..
tostring(AVP_get("fred")) .. "\n");
-- NOW … AVP_get("jimmy") returns "Old_mcDonald" which is what
"bingo" is set to .. WHY IS avp(jimmy) returning this?
xlog("********** ---> INVITE test from lua -- AVP_get(jimmy) ="
.. tostring(AVP_get("jimmy")) .. "\n");
xlog("********** ---> INVITE test from lua -- filemtime =" ..
filemtime("/root/foo.dump") .. "\n");
return 0;
end

Output
