Hi ,

I am working on Kamailio 4.0.1

We are trying load for presence subscribe with 1 cps(calls per second) using sipp , our setup is as below

No of children in both proxy and presence server is 4

DB mode is 3 in presence server

Expires is set to 3600 in subscribe request

May I know how many cps is  supported for presence?

Please let me know why load is failing.
