Too many files open #1

Closed typemismatch closed 8 years ago

typemismatch commented 8 years ago

I get a Too many files open with 125/5 test run. Outside of that is has been working great.

Nice to hear it's been useful. I got the same error at some point, when I increased the number of users (I don't remember the exact number, though). It got fixed by increasing the size of my EC2 instance to a t2.medium or t2.large. This is for the instance that is running Locust and generating load. What infrastructure are you using for this test?

I'm running it on an m4.large - I just spun up a bunch of them to get around that issue. I'll try a bigger size and see if it helps. Next I'm going to wrap this into a docker image and then run it on a cluster :)

too many open files is an os configuration item.
