This has been a >common approach for unix apps. yes, but running with SCHED_FIFO and calling mlockall has not been a common approach for unix apps. and because unix systems have made it difficult to grant applications permissions to use these capabilities with root permission somehow getting involved, adding these to a client-server design poses some very difficult questions. ultimately, running a...

...MMV. Whenever communication is done to an as-root app then the risk *is* increased (I treat that as fact). The point I was making with ices is that realtime scheduling is the only aspect that requires root (in general). For jackd I can see mlock being a possible problem if you dropped root privs, mlockall should be ok, but I haven't done much with that. > >What I can say is that ices tries to acquire realtime scheduling if > >enabled (default is yes) which may or may not fail, but if root is used > > what ices does is mostly irrelevant to JACK. the thread that handles > au...

Hi, I have OpenSolaris on an Amd64 Asus-A8NE with 2gig of Rams and 4x320 gig sata drives in raidz1. With dd, I can write at quasi disk maximum speed of 80meg each for a total of 250meg/s if I have no Xsession at all (only console tty). But as soon as I have an Xsession running, the write speed drops to about 120MB/s. Its even worse if I have a VBoxHeadless running with an idle win2k3 inside. It

Hi, secpwgen is always reporting "mlock: Cannot allocate memory" even with user root. CentOS 6.2. Problem with selinux? Thank you for help in advance. Best regards Helmut Drodofsky

Occasionally stopping amd freezes my system. It's a rare occurrence, and I haven't found a reliable way to reproduce it. It's also a real freeze, so there's no way to get into the debugger or grab a core dump. I only can perform the 4 seconds hard shutdown to revive the system. I run amd through sysutils/automounter, which is a scripting solution that generates an amd.map file

Linux does not treat various kinds of memory pages differently. If you want a daemon to be fully in core, call mlockall(). Here's one way to do that without changing the daemon's source: http://superuser.com/questions/196725/how-to-mlock-all-pages-of-a-process-tree-from-console (I've always only done this with my own code explicitly calling mlock) If you don't explicitly lock things into memory, f...

I have been doing a lot of reading forums and elsewhere but am somehow unable to connect the dots. Here is what I am trying to accomplish initially and then wish for it to grow bigger from here on. I have two POTS (Analog) line that would connect to the Asterisk Box. I have, to begin with 5 IP phones (PoE), all connected to a switch. Asterisk Box with a LAN card also connects to the same switch.

c:\APPS\TINC\tincd.exe --mlock --net=mynet --config=C:\APPS\tinc\mynet Without --mlock, the service starts OK. With --mlock, the service fails to start.

The patches following do indeed allow you to compile nbdkit.exe, but it does not actually work yet. I'm posting this experimental series more as a work in progress and to get feedback. Note this does not require Windows itself to build or test. You can cross-compile it using mingw64-* packages on Fedora or Debian, and test it [spoiler alert: it fails] using Wine. Rich.
