similar to: sysctl_out_proc() race in stable w/ patch

My wife got the following from a system running (effectively) 4.8-RELEASE (I built/installed world just before the kernel version was updated from 4.8-RC to 4.8-RELEASE). I gather she made a few attempts to get mozilla to start and then the system panic'd. According to the crashdump, p->p_leader is NULL but according to the code, this can never happen. This is a UP Athlon XP-1800 with

I''ve found what I think is a deadlock in the dtrace fork code. My only Solaris test machine is a single cpu box, where I have been unable to reproduce in the field so far. I''ve been able to reproduce on other platforms. Here is the scenario. You''ve got a target process, which has static probes. It is calling fork(), which causes it to end up at line 330 in fork.c:

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

Hi, I need some help to understand a backtrace. The situation is as follows: A diskless system acting as a kind of bandwithshaping firewall with both ipfw2 and ipfilter active at the same time. Ipfilter is used for port adress translation. The system panics about once every 6 hours. The network load is very low, only one Windows XP machine is connected but not actively used. I added a disk

Did cvsup on a machine that does just mail processing (well, a lot of spam scanning) and it crashed not too much later. This kernel does not include MFC src/sys/kern/sys_process.c revisions 1.111 and 1.112: Use kmem_alloc_nofault() rather than kmem_alloc_pageable() in procfs_rwmem(). Use vm_page_hold() in place of vm_page_wire() since the page can be freed. Don't hold extra

Hello, I see a reproducable panic when doing ibping and aborting it with ^C. My setup is two machines with Mellanox Infinihost III HCAs (one Linux one FreeBSD) connected back-to-back. Details below. I can upload 2 crash dumps, if this is useful. For some reason the port doesn't become ACTIVE, so no packets arrive, but that is probably unrelated. % uname -a FreeBSD cosel.inf.tu-dresden.de

Hi, I recently noticed that kldstat(8) started to dump core for me on RELENG_7. I traced the problem down to kldstat(2). r182231 (DTrace MFC) introduced a new version of kld_file_stat struct and added some code to support the old version of the structure in kldstat(). In the new code the old structure is known as kld_file_stat_1. Unfortunately there's a bug in this code: kldstat() copies

Just to let people know what my big picture is, I''m trying to write a script that will let me run a program, and name a progeny of that program that I want to debug. My script should find the first occurrence of that progeny, and run it until it finishes initializing the runtime linker, but stop it before it runs any shared library startup routines. (Failing that, I''d be okay

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

Hi, I''m trying to use dtrace to signal threads in my app when certain events happen, and the raise() action seemed adequate -- looking at the kernel sources, it sends a signal to the currently executing thread, and a quick microbenchmark confirmed this. However, further testing showed that if lots of threads hit the event simultaneously, the signal only gets delivered once, and may also
