Box with fresh RELENG_7 panic under heavy network load (more than 50k connections). This panics seems to be senfile(2) related, because when sendfile disabled in nginx, I can't reproduce the problem. Backtrace in all cases like this: # kgdb kernel /spool/crash/vmcore.1 GNU gdb 6.1.1 [FreeBSD] Copyright 2004 Free Software Foundation, Inc. GDB is free software, covered by the GNU General

I'm running a few servers sitting on top of a NetAPP file server ? everything runs great, but periodically I'm getting: nfs_getpages: error 13 vm_fault: pager read error, pid 11355 (https) errors on my screen ? not always same pid ? the annoying part is that it seems to always affect the same jail that is running .. if I shutdown all jails on that physical server, everything shuts down

ZFS works really stable on FreeBSD, but I''m biggest problem is how to control ZFS memory usage. I''ve no idea how to leash that beast. FreeBSD has a backpresure mechanism. I can register my function so it will be called when there are memory problems, which I do. I using it for ARC layer. Even with this in place under heavy load the kernel panics, because memory with KM_SLEEP

I woke up to a frozen box this morning - it froze up a few more times before I got a handle on it. Basically, the box runs idle but refuses to do disk IO, or does it -very- slowly. Top shows processes stuck in 'ffsvget', 'inode', and 'vlruwk' state. I can get the box responsive again by setting sysctl kern.maxvnods=100000. It starts up with kern.maxnodes=36079. I

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

i need to get inodeno on ZFS and i am not able to find how to find it in kernel at vfs layer. i have vnode pointer and i am doing VTOZ to get znode but printing z_id from znode pointer gives me deadbeef(unitialized) , can somebody point me how to get that? i looked at zfs_getattr code and it does similar thing which i am doing but its able to get me inode no in getattribute structure(node

Hey everyone, I'm hoping someone can point me in the right direction. I'm running a 6.1 box with mac_bsdextended compiled. I've created my ugidfw rules, and all seems well in the universe. I've got rules set up so the web process uid 80 and gid 80 can only read uid 1010 and gid 1010 owned files. When the web server tries to do something else, it throws an error such as:

I have a script where I can freely reference struct nameidata*, struct vnode*, etc. on Snow Leopard. How does DTrace know about these data types? I understand things like #pragma D depends_on library darwin.d where darwin.d has typedefs. I can''t find definitions of nameidata and vnode in any D scripts, though. How does it work? Thanks, Joel --- firefox for android!

I think I've read somewhere about panic during early root mount, fsck etc..

Hey all - Just a quick one... Is there any plan to update the mdb ::memstat dcmd to present ZFS buffers as part of the summary? At present, we get something like: > ::memstat Page Summary Pages MB %Tot ------------ ---------------- ---------------- ---- Kernel 28859 112 13% Anon 34230

Hi, I've done some strange(?) experiments and I managed to get a panic of type "baddir" and just now another one that only rebooted my system instantly without writing a vmcore. I don't know if this is important. I could not find any information on how gvinum detects failed hard disks. That's why I tried something really simple. Steps to reproduce: 1) dd if=/dev/zero of=a

Normally the FreeBSD Project tries very hard to avoid ABI breakage in "Stable Branches". However occasionally the fix for a bug can not be implemented without ABI breakage, and it is decided that the fix warrants the impact of the ABI breakage. We have one of those situations coming along for RELENG_7 (what will become FreeBSD 7.1). The ABI breakage should only impact kernel modules

Hi All, Is there a simple way to list all currently open file descriptors ? TIA.. Regards, Venkat -- This message posted from opensolaris.org

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

Hi This array is defined in compiler-rt: InstrProfilingValue.c but I can’t find where it is used? And the comment on it does not say much about why we need it either. Can someone explain why we need this and where it is used? /* A shared static pool in addition to the vnodes statically * allocated by the compiler. */ COMPILER_RT_VISIBILITY ValueProfNode
