Support » Fixing WordPress » core dump files in wordpress install

  • Hi,

    I was recently surprised to see that my wordpress install folders have swelled up in size like anything. I have 3 installs of WP and I noticed that in the root of each install there were dump files with a name pattern “core.*” and with sizes to the tune of 12MB each.

    I asked my host and he said WP often generates such files and advised deleting them. I have never seen such a thing happening before WP 2.5.1. Does WP really generates these files or is it a bug?

    Example from one install:
    core.6845 12 MB 0600
    core.6964 14 MB 0600

    The File Type is shown as: ELF 32-bit LSB core file Intel 80386, version 1 (SYSV), SVR4-style, from ‘php’

    Core dumps are not specifically generated by WordPress, however it’s NOT a bug that they are made either. They serve a purpose. (Not to suggest that a bug might not be causing them)

    Think of them like a the result of the bsod in Windows.

    If you are so inclined here is some further reading:

    Your host, fwiw, is sort of full of crap — what they should have said was that something is crashing, PHP, or Apache, etc…, and that they need to debug it. Thats what core dumps are for.


    So, what exactly would you do with the core dump file of WordPress ?




    delete them. or read them, but they wont mean anything to you.

    and like I said, core dumps arent caused by wordpress.
