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.

 

Cheers,

 

Henning

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

 

Hi,

 

I've noticed more than 14 Gb RSS memory consumption during load test (8000 WSS clients send registrations):

Shared memory consumption is:

# /var/lib/ums/sbin/kamcmd -s tcp:localhost:2048 stats.get_statistics shmem:
shmem:fragments = 4
shmem:free_size = 1291909000
shmem:max_used_size = 855663448
shmem:real_used_size = 855574648
shmem:total_size = 2147483648
shmem:used_size = 818055392

 

 

Also, I don't understand why kamailio maps more than 2 GB per every child process:

Any ideas what is happening here?
