nscd in 6.x?
Hi all, I want to implement nscd in a lot of servers which has diferents releseases of 6.x and 7.x branches. No problem with 7.x branches: nscd seems part of the system now: # whereis nscd uname -r nscd: /usr/sbin/nscd /usr/share/man/man8/nscd.8.gz /usr/src/usr.sbin/nscd 7.0-RELEASE-p4 But not appears in 6.2: # whereis nscd uname -r nscd: 6.2-RELEASE-p11 or 6.3 # whereis nscd uname -r nscd: 6.3-RELEASE-p3 Moreover I've updated the src of one 6.3 to see if this it was included in 6.4 sources but also it's not there: # grep nscd /usr/src/sbin/ ¿Can I use nscd in 6.x branch? ¿Is there some 'alternative'? I've read about cached but I don't find anywhere in 6.3 (for example); the only one reference I've found is the port /usr/ports/databases/memcached, but I think it's not nscd-related at all. -- Thanks, Jordi Espasa Clofent ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to freebsd-stable-unsubscr...@freebsd.org

A new version of firmware should be coming out from Dell that should resolve this issue.

Is there something I can do to force the system to rescan for my mouse to save me from crawling around on the floor whenever I reboot? Do you have Legacy USB support enabled in the BIOS? If so, try turning it off. I tried it both ways. I get some waiting for BIOS to give up control messages for some of my /dev/usb devices in the dmesg now too, even with legacy USB support disabled in the BIOS. Thanks for the suggestions.

livelocks and deadlocks on 8.0BETA2
I have a quad-core system that I updated to 8.0 about 2 weeks ago. It ran fine until yesterday when I used the PATA/ATAPI DVD drive to read a disk. Then the fun began. I saw two totally different presentations, but I hope that they both are manifestations of the same problem. First, the livelock. When attempting to play video off of the disk (xine or mplayer) while the CPU was busy, xorg would lock up solid. All CPUs were running a threaded code that run them all at 100%, but they were running niced to 10. Couldn't kill xorg, even with a 'kill -9'. Ate 100% of a CPU, though the CPU it was running on changed periodically. Could not switch to vty. The display was frozen and I could do nothing from the console. I could log in from another system and the system behaved normally. While I could not free the console, I could and did manage to shut down the system and reboot. This happened repeatedly and within a few seconds of starting the video playing. Now the deadlock. This one is weird in one instance. I had finished with a disk and unmounted it. No problems. Then I ejected the unmounted disk. (Yes, df(1) did not show it.) After the disk ejected, the system deadlocked. Frozen completely. Could not even ping it on the net, so it was in the kernel. I had no luck doing anything, so I had to kill power. Then it got worse. The second time this happened, I inserted an erased DVD while the system was in POST. The system started to boot, but, shortly after probing acd0, while the boot was waiting for: usbus7 usbus6 usbus5 usbus4 usbus3 usbus2 usbus1 usbus0, and about the time it should have probed for cd0 (atapicam), the system locked up and would not finish the boot. This is prior to mounting root. After several repeats of this, I ejected the disk from the drive and it booted just fine. Clearly something with ATAPI is not happy. Should I not be using atapicam with 8.0? I won't have access to this system until next Tuesday and the time I have to tinker will be limited, but I can try setting up to break into the debugger (if the system is even seeing the keyboard) or do something else to get an idea of what is going on. -- R.

This all was happening while not paying attention to the NFS mount and that mount being various directories under /var and including /var/mail. A little deeper I eventually came across and what made me feel pretty stupid is that the $SHELL whether it be csh, ksh, bash or sh checks for mail on command completion or invocation and being so that the NFS mount stopped responding the process would hang until the mount came back or the machine was rebooted. I continued for a while using /var/mail over NFS while setting or unset mail variables for the shell. You may also want to check into whether something is trying to acquire a lock on a file over that NFS mount which could accrue some extra time making it seem like a process is hung. -- - (2^(N-1)) ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to freebsd-stable-unsubscr...@freebsd.org
