Hi hackers, I am running some test programs to check the max number of sockets I can open on a machine. Don't ask why! :) The max number that I reached was 7318. I get 'Too many open files' when trying to open more. And I am curious why. I have bumped the following sysctl vars: (17:32) root@(alice)[~] sysctl kern.maxfiles kern.maxfiles: 15000 (17:32) root@(alice)[~] sysctl kern.maxfilesperproc kern.maxfilesperproc: 15000 (17:33) root@(alice)[~] sysctl kern.ipc.maxsockets kern.ipc.maxsockets: 15000 When trying to run 'sysctl kern.openfiles' I get indeed: (17:29) root@(alice)[~] sysctl kern.openfiles kern.openfiles: 7419 So there aren't any other processes 'eating up' the rest of the sockets. The other question that I've got is related to the 'vm.zone': (17:28) root@(alice)[~] sysctl vm.zone vm.zone: ITEM SIZE LIMIT USED FREE REQUESTS .... socket: 192, 15000, 7348, 33, 43978 I thought that the LIMIT == USED + FREE, but it seems it's not that way... Could somebody explain?
