kern.ipc.maxpipekva
I'm getting error messages about this when trying to run my program. As far as I know, I don't use IPC at all, although I dare say it is used in one of the libraries that are linked in. After googling for this error, I edited /boot/loader.conf to set it to 6500 (a nice big number?), and now if I do: sysctl kern.ipc.maxpipekva I see: kern.ipc.maxpipekva: 6500 but I still get the message. I also get a lot of messages saying: Fatal error `Cannot create kernel pipe' at line 294 in file /usr/src/lib/libc_r/uthread/uthread_init.c (error = 24) Why does this occur, and what can i do about it?

Tracking down "kern.ipc.maxpipekva exceeded"
Hi, For some time one of my machines in plaged be becoming completely unresponsive after different amounts of time (several hours up to several days). Symptoms: Machine is PINGable, but no access over the network is possible (neither ssh-login nor http-access). /var/log/messages: May 11 12:11:00 io kernel: kern.ipc.maxpipekva exceeded; see tuning(7) maxproc limit exceeded by uid 0, please see tuning(7) and login.conf(5). (tons of both) and finally May 11 12:42:03 io kernel: maxproc May 11 12:42:03 io kernel: limit exceede May 11 12:42:03 io kernel: d by uid May 11 12:42:03 io kernel: 0, ple May 11 12:42:03 io kernel: se see tun May 11 12:42:03 io kernel: ng(7) and l May 11 12:42:03 io kernel: ogin.conf May 11 12:42:03 io kernel: (5). May 11 12:42:03 io kernel: >From that time on I can't log in any more, not even from the console. When rebooting the box via ctl-alt-del, before shutdown, it fails to sync buffers on shutdown (counts down to 1 and stays there) and finally gives up - requiring an fsck on reboot. Please note that the box does *not* crash completely, nor do I get a kernel panic though. The system is running "5.4-STABLE FreeBSD 5.4-STABLE #0: Sat Apr 16 10:19:26 CEST 2005" but this problem has been there since I first installed 5.3 on the box. So my primary question is: How do I track down the cause of the problem, i.e. which program/process is responsible for "kern.ipc.maxpipekva" to be exceeded?

Re: kern.ipc.maxpipekva exceeded, error
Hi Puna, This looks like there occured a looping recursion, there is definately something wrong with your ports.
