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

Hi,
We have observed increased memory utilization in Kamailio, It
increases every day, even though traffic is not increased. We are
using Kamailio+RTPEngine in our setup.

Any idea which could cause a memory leak. Does any of the module
cause an issue?
Thanks in Advance.
