### Description
<!--
Explain what you did, what you expected to happen, and what actually happened.
-->
We are using lua base routing with app_lua. We are seeing that our memory-utilization on
that system continuously getting increase. our route.lua will have all routing logic same
as
https://github.com/kamailio/kamailio/blob/master/misc/examples/kemi/kamaili…
we are using following set of modules
loadmodule "tm.so"
loadmodule "rr.so"
loadmodule "pv.so"
loadmodule "tmx.so"
loadmodule "sl.so"
loadmodule "maxfwd.so"
loadmodule "nathelper.so"
loadmodule "textops.so"
loadmodule "siputils.so"
loadmodule "xlog.so"
loadmodule "sanity.so"
loadmodule "path.so"
loadmodule "jsonrpcs.so"
loadmodule "app_lua.so"
loadmodule "dispatcher.so"
loadmodule "json.so"
loadmodule "cfg_rpc.so"
loadmodule "ctl.so"
loadmodule "ipops.so"
loadmodule "http_async_client.so"
loadmodule "dialog.so"
# ----------------- setting module-specific parameters ---------------
# ----- rr params -----
# set next param to 1 to add value to ;lr param (helps with some UAs)
modparam("rr", "enable_full_lr", 0)
# do not append from tag to the RR (no need for this script)
modparam("rr", "append_fromtag", 1)
# ----- dispatcher params -----
modparam("dispatcher", "list_file", DISPATCHER_FILE)
modparam("dispatcher", "ds_probing_mode", 1)
modparam("dispatcher", "flags", 2)
modparam("dispatcher", "ds_ping_interval", 10)
modparam("dispatcher", "ds_ping_from", "sip:ping@test.com")
# ----- nathelper params ----
modparam("nathelper", "received_avp", "$avp(s:rcv)")
# ----- http_async_client -------
# ---- number of worker process for async req and res
modparam("http_async_client", "workers", 4)
# ----- ctl ------
modparam("ctl", "binrpc", "tcp:MY_IP_ADDR:2086")
# ----- app_lua params ----
modparam("app_lua", "reload", 1)
modparam("app_lua", "load", ROUTE_LUA)
# ---- dialog params ----
modparam("dialog", "enable_stats", 1)
modparam("dialog", "dlg_flag", 4)
modparam("dialog", "event_callback", "ksr_dialog_event")
cfgengine "lua"
### Troubleshooting
#### Reproduction
We can easily reproduce by loading app_lua with kamailio-basic-kemi-lua.lua
https://github.com/kamailio/kamailio/blob/master/misc/examples/kemi/kamaili…
<!--
If the issue can be reproduced, describe how it can be done.

It is not clear what type of memory leaks? Is it the on managed by kamailio in pkg or shm?
Or is the system memory? Because in the shell script you use system's `free`.
To watch kamailio's shm memory do:
```
kamctl stats shmem
```
For pkg:
```
kamctl rpc pkg.stats
```
If it is system memory, then the logs of kamailio related to qm_status are irrelevant.
So once it is clarified what memory type is leaking, then we can provide next steps to
analyze the issue.

we are seeing the memory related system increasing to 97% so its might the case that
system memory getting increase.

Are you loading and using any Lua modules/libraries?
Or it is just using the KSR module exported by Kamailio? Are you issuing often reloads of
lua script?
The way to troubleshoot leak of system memory is to run kamailio via valgrind
(http://valgrind.org/). Do not forget you have to track forked processes:
```
valgrind --trace-children=yes ...
```

yeah sure i will run that one. i am using both ways
1. using lua modules
2. without using lua modules
both ways i can figure out that system memory getting increases.

I do not see any new relevant information attached here, have you run with valgrind as I
metioned in my previous comment? It should give the report if there are leaks for system
memory.

/usr/bin/valgrind --tool=memcheck --log-file=vg.log --leak-check=full --trace-children=yes

Did you run and test it long enough that the memory increased a lot? I checked the logs
for couple of PIDs and no relevant leak is reported.
Maybe you can make minimal kamailio.cfg and kemi lua script along with a sipp scenario
that I can use and reproduce here.

An update -- I pushed a commit to restore the Lua execution stack. Try with latest master
and if the issue is still expose, try to give the minimal configs and scripts to
reproduce, as I wrote in my previous comment.

So, I assume it is still there in the master branch, after my last commit realted to
app_lua. I will try to reproduce here with the first available time frame.

Didn't get the chance to look at it, being in a trip to USA (Cluecon). Hope to get
back to it soon, after returning.

@miconda please look into this one. because now a days developer already started to move
for kamailio in lua. if there is memory leak then it will be great issue.

New subject: [kamailio/kamailio] Memory utilization getting increase with lua routing (#1577)
I could not see any memory use increase when I ran a sipsak flood for more than 10min on a
config based on the one you posted on the comment:
* https://github.com/kamailio/kamailio/issues/1577#issuecomment-404720655
I removed dispatcher and nathelper modules, becuase they were not used in the Lua
ksr_request_route() at all.
There is no memory usage increase reported by `top` or by the shell script you provided in
a previous comment.
Are you sure you tested with latest master that includes the commit eb96593 ?

i did not get a chance to test. but surely i will test by end of week. will you please
also conclude about using modular approach with kemi lua.

Still i am seeing the memory continuously increasing. I tested with modular approach using
app_lua mentioned by sipgate. I will test app_lua with LuaJIT. Also will be trying with
one simple lua.

You haven't attached the valgrind output.
I tested with the example you provided at:
* https://github.com/kamailio/kamailio/issues/1577#issuecomment-404720655
and I could not spot any leak after sending thousands of requests.
I am not a Lua expert to comment on others libs/packages/approaches. There can be libs out
there in the Lua world that can leak, it is not kamailio's role to fix them. Use
kamailio with lua and functions exported by kamailio to lua, only then if there is a leak
can be fixed in kamailio.

Closing, no follow up in one month, but also the code evolved since the issue was opened.
Test with master branch and if still problems, open a new issue here with the details
specific for it.
