Core dumps appearing in WP folder (7 posts)

    I am getting core dump files eg. core.29564 appearing in my WP top level folder and is slowly filling up my server. They vary in size from about 9 to 11Mb. I can't see any problems, my blog appears to working fine, it seems to be that every time my blog is accessed it generates a core.XXXXX file. I deactivated all my plug-ins but it has had no effect. Has anyone had or seen this problem before ?

    Kind Regards
    Gary

    Google search: core dump php

    Here's what I'd do: Try a clean install of WordPress (delete all old files, re-upload, new, empty database). Make sure you backup your blog (export all posts and also back up the database).

    If the dumps still occurs, then contact your webhost's support, because this looks like a server issue.

    Check the content of the core dump files for clues. It is probably because one of your binaries (i.e. unzip, imagemagick) is not working correctly. If the core files point back to php, then it could be a a memory limit problem, a g2 bug, or a php bug.

    you cannot just open a core dump and read it -- you need gdb

    Like GaryTapp, I'm finding core dumps in in the WP top level directory. The blog appears to be working as it should, and the plugins are the same used on other WP installs. I wondered if it was a bad fantastico install. I took scribblerguy's advice, did the back up, and uninstalled wp. Fantastico wouldn't reinstall for some reason, so, installed WP from scratch (was easier than I thought). Downloaded new plugins, installed them, re-entered the postings from scratch (luckily only a few), re-installed the theme (Shades of Gray). Practical upshot: effectively a brand new blog - http://vanquish.ako.net.nz

    The core dumps continue :(

    I flicked a note to my host and they replied with:

    I'm afraid the core file is not telling much about the issues there , I tried to debug it with GDB and here is the info I could gather

    (gdb)

    so we know that these cores are generated by /usr/bin/php/home/akonet/public_html/vanquish/index.php but I tried to do any back traces with no luck, only wordpress will know how to debug it, they sure have the symbol tables.

    Where to from here?
