I am running a geth node following this on Ubuntu 16.04 following this https://goo.gl/FvAisy I am using locust to run load tests on this node.
However, as soon as the user count reaches 1024 the tests begin to fail and I start receving connection error. Basically, the node starts rejecting connections.
I tried to increase the
$ ulimit -n 64000
However, I still face the same error. Is there any setting on the RPC server or any other OS configuration that I should be testing?
