similar to: DTrace and shared memory id

Every time ogg123 -bXXX is run, it creates another shared memory segment but fails to destroy it on exit. Thus an increasing number of shm segments keeps piling up and eat all the (often rather limited amount of) available shared memory. The patch below corrects this and also fixes the bizarre abuse of stat() permission bits for shmget(). On systems that support it, I'd very much like to

Linux 2.2 (and probably others) have a deficient mmap which has caused a number of problems (e.g. bug #285). A workaround is in development, but it would be helpful to have a configure test to detect the bad mmaps(). Any takers? -d

(Hope this is the right place to post this message.) Hi all, I am working on a small movie player which can play full screen movie using Xserver. It works fine in Single Head Mode. But is I set the Xserver in Dual Head Mode. I can't see any thing on both screens. The Code to Init the display is shown as below: > display = XOpenDisplay(NULL); > if (display == NULL) >

The patch below adds: - acinclude.m4: A new macro A_FUNC_SMMAP to check that sharing pages through mmap() works. This is taken from Joerg Schilling's star. - configure.in: A_FUNC_SMMAP - ogg123/buffer.c: If we have a working mmap(), use it to create a region of shared memory instead of using System V IPC. Works on BSD. Should also work on SVR4 and offspring (Solaris), and Linux.

Dear Daniel, Thank you for your email. According to your suggestion, I tried to use the shared memory filesystem for data exchange between the host machine and the container. The steps are as follows: 1) create an empty file in the host machine (/tmp1/file1). 2) run #chmod 777 /tmp1 and #chmod 777 /tmp1/file1. 3) expose /tmp1 to the container by configuring the container with the following XML

In CentOS 6.7, if I start emacs from a terminal session, I always see a message, "(emacs:{PID}): Gdk-WARNING **: shmget failed: error 28 (No space left on device)" The message is also logged to .xsession-errors, and that occurs regardless of how emacs is started. The same thing occurs with SELinux in permissive mode. Emacs version is emacs-23.1-28.el6.x86_64 . Output from strace

hi, I tried to make huge page request in Fedora x86_64 PV guest using xen 4.1 unstable and it crashed(crash info given below) I had enabled superpages in config file I had also set hugepages parameter at boot time for the PV Dom U By excuting # cat /proc/mem_info | grep Huge gave me that there are 10 free huge pages available , still the domain crashed.

How can I tell if this is normal behaviour? Oracle imports are horribly slow, an order of magnitude slower than on the same hardware with a slower disk array and Solaris 9. What I can look for to see where the problem lies? The server is 99% idle right now, with one database running. Each sample is about 5 seconds. I''ve tried setting kernel parameters despite the docs saying that

Dear all, In my system, two containers need to exchange data as quick as possible and the two containers are hosted by the same physical machine, I wonder if socket is the only method for communication between containers? Thank you. Cheng Wang

I have a machine with fairly much memory 16GB and I get shmget failed: error 28 (No space left on device).

We''re running a Solaris 10 container, with an Oracle 9.2.0.4 database - every 5-10 min, an Oracle process shoots up (using 20% + CPU) and then goes down in CPU %, doing a [i]pollsys [/i](see it via dtruss). I tried using some of the trace scripts in the Dtracetoolkit to see what the process is doing, but without any luck - also tried with the following, but dtrace process goes up to 30%

Hi, I want to write a package where I would use shared memory for some vectors Any suggestion is appreciated... I wonder if the right approach would be to modify add a modified version of the allocVector(SEXPTYPE type, int length) function specifically shared_mem_id = shmget(shared_mem_key, SHM_SIZE, IPC_CREAT);
