[SR-Users] Memory issue?

[Mititelu Stefan]

Hi Igor,

Yes, it's caused by lack of shm.

I don't know if there is a proper shm value. Depending on how many modules
are loaded on kamailio and how much shm a module might use over time, more
or less shm should be used. In your particular case, depending on how much
userblacklist table should grow, you should adjust the startup shm value.

Thank you for your detailed feedback on the segfault; the fix it's on its
way and will be backported.

Stefan
