Hi Mack,

looks indeed like an issue. Can you try with git master commit f50177003c21f. If your test is also ok, I will backport to stable branch

Based on my tests, the memory leak is only exposed when you are using domain attributes, which are stored in the domain_attrs table.  I wanted to see if anymore else is running into this issue.

Reproducible use case:

1) Insert the following into the database

insert into domain values (null,"aprilco.com<http://aprilco.com>","aprilco.com<http://aprilco.com>",now());
insert into domain_attrs values (null,"aprilco.com<http://aprilco.com>","pbx_type",0,"0",now());
insert into domain_attrs values (null,"aprilco.com<http://aprilco.com>","pbx_id",0,"65",now());

2) Open a new terminal window and execute:

watch "kamcmd core.shmmem"

3) Open up another terminal windows and execute:

while true; do kamcmd domain.reload; done

Expected Results:

You will see the shared memory being allocated, but never freed.  The more entries you have in the domain_attrs table, the faster it will run out of memory.
