Python on OSx - set the new limit of open files

I want to set a new limit of possible open files with the command:

import resource

    resource.setrlimit(RLIMIT_NOFILE, (resource.RLIM_INFINITY, resource.RLIM_INFINITY))

However, I'm getting an error: ValueError: current limit exceeds maximum limit Is there any way to overcome this and set a new limit on OS X?

Solution

  • You can only do it like this in Mac os.

    import resource
target_procs = 10240
your_procs = ???
real_procs = min(target_procs, your_procs)
resource.setrlimit(RLIMIT_NOFILE, real_procs, resource.RLIM_INFINITY))
