Re: [sr-dev] High memory consumption during load tests

Hello, Please also give the Kamailio version that you are using, just to sort out eventual already fixed memory leaks. About the question regarding the 2GB memory mapping – according to your configuration this should be shared memory (not assuming a memory leak in system memory because of a library etc..). So, it should be not 2GB per process, but 2GB in total. And the memory is also not completely used, only 855MB of it: shmem:real_used_size = 855.574.648 Maximum private per process memory is according to your cfg 12 MB.
