Dear Clearwater Developers: Currently, I'm running clearwater sip stress test against a small clearwater cluster. I'm currently encountering some problems about the test load. Could you please help me explain my problem?
My test environment consists of 4 VMs interconnected by a LAN network, running Bono, Sprout, Homestead and Homer respectively. I have another VM running the clearwater-sip-stress package. This additional VM generates sip traffic to the clearwater cluster. I provisioned Homestead and Homer node with 200000 subscribers. VMs running Bono and Sprout are configured with 2 cores and 4GB RAM. VMs running Homestead and Homer are configured with 4 cores and 8GB RAM because I notice that the cassandra service will consume a lot of memory and CPU resource. Currently, when sip stress node generates traffic for 80000 or 90000 subscribers following the steps in the clearwater doc. The whole cluster runs smoothly. But when sip stress node generates traffic for 100000 subscribers, the cluster can't operate normally. First, I can observe many errors from the call_load2_xxx_errors.log (where xxx is the current sipp pid). Second, the Sprout node will constantly restart itself because of signal 6 or signal 11. My problem is this: according to the performance page on the official website, it seems that each sprout node can handle 551k Subscribers and 500k BHCA, which is much larger than my current statistics. Is the phenomena that I encounter when I run stress test for 100000 subscribers caused by Sprout Node overloading or some other errors? Thank you very much!
