Hello,
can you provide more details about what memory leak you talk? Is it
about shared memory (shm) or private memory (pkg) managed by kamailio or
by the system memory? How do you observed there is a leak? Did you get
error messages in Kamailio logs? If yes, can you paste them here?
Cheers,
Daniel
