Hi, I am going to merge latest batch of the nullfs improvements into stable/9. This will bring up significant performance enchancements due to use of the shared locks for lookups if the lower layer supports it, much better caching on the nullfs layer, and proper handling of the text segments on the nullfs. Also, it should improve the error recovery and some corner cases with locking.

While trying to speed up nanobsd builds, I mounted /usr/obj on a ramdisk and found my box crashing. Thinking it might be hardware, I tried a separate machine, but with the same results. I have 4G of ram (i386). Am I just running out of some kernel memory ? If so, is there anything I can adjust to prevent this, yet still use mfs in this way ? mdconfig -a -t malloc -s 1800M newfs /dev/md0

I'm trying to make devd run an stty command whenever a USB serial device is attached. Unfortunately, $device-name is ucom[0-9] and the device names are /dev/cuaU[0-9] - how do I get the correct name in the device action? I haven't found a way to extract the number by itself, so I'm stuck with specifying a separate rule for each number, like so: attach 100 { device-name

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

Any way to check if another proc has run or been run by a proc that is setuid or seteuid?

Hello! Currently, when a program built without OpenMP (-fopenmp) is trying to dlopen a library, built with the feature, the result is a crash from "bad system call": #0 0x00000008009a223c in ksem_init () from /lib/libc.so.7 #1 0x0000000800998a8f in sem_init () from /lib/libc.so.7 #2 0x00000008011a6537 in omp_get_nested () from /usr/lib/libgomp.so.1 #3

I'm failing to understand how getrusage() works, which is a bit perplexing, because it doesn't seem like it would be terribly complicated. I've attached the code. My aim is to verify that I can use getrusage() to do (admittedly crude) instrumentation of which functions in my program are allocating lots of memory[1]. So I figure I can call getrusage() at various points and look at

I'm running 9.2-RC4 on a handful of desktop and server machines (both i386 and amd64). I have seen three panics (all vm_page_unwire) on one of those systems only (amd64 server) during the past week. The first two panics were triggered when shutting down the ntpd daemon (a recent development snapshot version of ntpd: 4.2.7p387). Exiting a later release (p388) has not triggered the panic.

I wouldn't report this if not for one coincidence (which is described below). I have too little facts, so this is more of a mystery problem tale than a real problem report. There are two systems: 1. old, slow, i386, UP, 7-STABLE 2. new, fast, amd64, MP, 6.3-RELEASE Systems are located at different physical locations. What is common between them: 1. they both have the same backup strategy

Hello! My attempt to build openoffice.org-3 seems to be hanging. Pressing Ctrl-T produces: load: 0.11 cmd: tcsh 79759 [sleeping without queue] 0.00u 0.00s 0% 0k (tcsh is used by OOo's build-script). What is this "sleeping without queue" state, and why is process in it for so long? This is an 4-CPU amd64 system with 4Gb of RAM. Only 16% of the swap is currently in use and

Hello, Recently, the FreeBSD base system OpenSSH was upgraded to OpenSSH_5.1p1 FreeBSD-20080901, OpenSSL 0.9.8e 23 Feb 2007 Before the upgrade, with OpenSSH_4.5p1 FreeBSD-20061110, OpenSSL 0.9.7e-p1 25 Oct 2004 I had no troubles connecting to the ssh server built-in into the HP Proliant G5 ILO management board, authenticating by id_dsa, v2 protocol. On that board, ssh server greets with

Running FreeBSD 8.3 -- and updating sources on a daily base and building everything -- I found a new APIC/ACPI problem introduced in the past week. I have a Toshiba Satellite U205 with an Intel Core Duo (not a Core 2). It used to work fine with both cores but then sometime in on the road to BSD 8.0 the machine began hanging. So I added to /boot/loader.conf hint.apic.0.disabled="1"

The redbuild boxes for redports are doing a very good and reliable job getting kernel panics out of 10.0: http://people.freebsd.org/~sbruno/redbuild_panic.txt Pretty frequent and pretty nasty.

Hello, I'm trying to investigate and solve some postgres latency spikes that I'm seeing as a result of some behaviour in the syncer. This is with FreeBSD 8.2 (with some local modifications and backports, r231160 in particular). The system has an LSI 9261-8i RAID controller (backed by mfi(4)) and the database and WALs are on separate volumes, a RAID 6 and a RAID 1 respectively. It has

I've been playing around with snapshots lately but I've got a problem on one of my servers running 7-STABLE amd64: FreeBSD paladin 7.1-PRERELEASE FreeBSD 7.1-PRERELEASE #8: Mon Nov 10 20:49:51 GMT 2008 tdb@paladin:/usr/obj/usr/src/sys/PALADIN amd64 I run the mksnap_ffs command to take the snapshot and some time later the system completely freezes up: paladin# cd /u2/.snap/ paladin#

...which deal with advisory locks. As such the impact should not cause many people problems. The work that will be MFCed fixes issues with filesystem advisory locks, and moves the advisory locks list from filesystem-private data structures into the vnode structure. The MFC will be done by Kostantin Belousov some time this coming Friday (August 1st, 2008) if you have concerns and want to watch for it. Thanks. -- Ken Smith - From there to here, from here to | kensmith@cse.buffalo.edu there, funny things are everywhere. |...

Hi, my FreeBSD-9/stable machine (FreeBSD freebsd-tower.goebo.site 9.1-PRERELEASE FreeBSD 9.1-PRERELEASE #2 r241044M: Sat Sep 29 12:52:01 CEST 2012 lbo@freebsd-tower.goebo.site:/usr/obj/usr/src/sys/GENERIC i386) crashes reproducibly when rsync-ing files to an NFSv4 share on the FreeBSD machine. The crash makes the system reboot. The crash creates files in /var/crash which may be obtained

Colleagues, one of my servers had to be rebooted uncleanly and then I have backgrounded fsck locked for more than an our in snaplk: 742 root 1 -4 4 1320K 688K snaplk 0:02 0.00% fsck_ufs File system in question is 200G gmirror on SATA. Usually making a snapshot (e.g., for making dumps) consumes 3-4 minutes for that fs, so it seems to me that filesystem is in a deadlock. Any

Hello, There it is, all my computers on FreeBSD 9.1-RELEASE had panic. I can just say there is a problem in the 9.1-RELEASE because I had no panic before. What afraid me is that my production server also panic'ed a few days ago, fortunately it does not appears so often. This is a panic that happened on my desktop computer, with a graphic card. The crash usually appears when X starts. GNU
