Hello,

We have noticed the exact issue on our own systems (Kamailio 5.8.2 on Ubuntu 
22.04.4 LTS). Every time we run

kamctl rpc tls.reload

the "shmem:used_size" output from the 'kamctl stats shmem' command increases by 
about 3.2MB.

This looks like a memory leak, so I tried to find which module could be 
increasing its memory use by running the following commands:

kamcmd mod.stats all shm
kamcmd pkg.stats
kamcmd mod.stats all pkg

but if there are any changes before and after the restart those are minimal and 
they do not amount to anything approximating 3.19 MB for every reload.

I have attached the before and after outputs of the above commands in case 
these help.
