    Our users were getting loads of core dumps appearing in their webspace which we have been cleaning out for about 5 days.

    php -v was showing this;

    PHP 4.4.2 (cli) (built: Mar 28 2006 20:10:58)

    *** glibc detected *** corrupted double-linked list: 0x08411120 ***

    By chance i commented out the zend directives from php.ini and restarted it. No more error.

    So if your wondering about all those core files i suggest you remove this version of Zend and install an earlier version as there seems to be some serious issues with it. We are also runnning RHEL4 on this server if that matters.

    Go on, have a guess
    Yup, I've seen various problems on some servers with v3 of Zend Opt. Others are fine. Seems to be a combination of included PHP modules that causes the problem. If you have versioning enabled, you could try recompiling PHP with it disabled, but that's just a guess at a module that commonly causes issues.

    Yes, versioning seems to be a problem with a number of 3rd party applications like Chilisoft for eg. I have started not including this module.
