Hi Daniel, from time to time there are reports that people run into issues after trying to load larger data sets into the memory (e.g. with routing tables). I also thought about the system package files, if its ok I would also check them to increase it as well to 128 MB.

I haven't noticed and such report on mailling lists or issue tracker later, whondering if it is some particular use case that can lead to this issue. Because a start of kamailio with default config file is using less than 3MB of shared memory, being plenty of space to fill up to 64MB with registrations, transactions, etc... states taken a few minutes ago with git master branch:     "shmem:max_used_size = 2836288",     "shmem:real_used_size = 2836288",     "shmem:used_size = 2594376" Then, my actual remark is that I think the new users tend to use the packages, which use init.d/systemd to start kamailio, and there are values for pkg and shm sizes in the unit files, so this change doesn't really make a difference, because kamailio is started with different -m and -M command line parameters.

Hi Daniel, I don't think that anybody might think that Kamailio is greedy with resources. A Raspberry Zero for 5 Dollar has 512 MB RAM and was released in 2015. Some years ago we also increased PKG memory default for similar reasons, so I think this is a reasonable change after all the years as well.

Personally I didn't meet any case lately where the default value has to be changed for shm and the defaults should be for the avearage use of Kamailio -- that's the reason I wanted to know about some of these cases. I do not want to get Kamailio look greedy in resources because the defaults are tuned for corner cases. I did increase many of the internal buffers/sizes whenerver there were related reports, but didn't noticed the default shm is even getting closer to being filled up for new comers playing with kamailio. If there is a need for such increase for new comers, I would rather keep the default in the source code lower and increase it in startup scripts. Who starts from command line is expected to have some knowledge about its parameters, easily set the -M and -m.
