redis-benchmark gives Too many open files in system when running with -c 100

[John-Ted]

Describe the bug

When building the redis native app, version 7.0.11, and attempting to benchmark it with redis-benchmark, the benchmark does not start and the app outputs Too many open files in system if I set 100 clients.

Steps to reproduce

I used https://github.com/unikraft/app-redis and unikraft/lib-redis#10, along with the other libraries necessary to compile redis-server.

I ran the benchmark with the command redis-benchmark -c 100 -q -h 172.44.0.2

Expected behavior

I expected the benchmark to run properly.

Hi! I'm a UT student working on a final project in my virtualization class where we have to contribute to an open source project. I was wondering I could get this issue assigned to me?
