Un petit script python pour tracer les limites
import platform
if 'linux' in platform.system().lower():
import resource # Linux only
limit_nofile = resource.getrlimit(resource.RLIMIT_NOFILE)
limit_nproc = resource.getrlimit(resource.RLIMIT_NPROC)
print 'Max number of opened files allowed:', limit_nofile
print 'Max number of processes allowed', limit_nproc
