    Seg fault every time a page tries to load, no pages loading. Also tried with PHP 4.3.10 & zend is updated.

    Oh, and the distro is FC2. Searched the forums through about 4 pages of results.

    We have found that Segmentation fault 11 is caused by hardware (mostly)
    Check out

    http://www.bitwizard.nl/sig11/

    We have found that Ram, or a frade cable would cause this error usually.
    If it was Apache, your error would show the httpd process instead of [notice]

    mmcache is not installed, just the Zend Optimizer.

    If it was a hardware problem, wouldn't I notice these segfaults elsewhere?!

    I can't see any segfaults anywhere else, and the operation of the server does not seem to be effected.

    SOLVED - I think...

    I checked my php.ini and in the Zend Optimizer config, it was loading both the thread-safe binary and the non-TS binary. This can't have been healthy, and it seems to have stopped the segfaulting.

    I will monitor the situation to see if I can find any more evidence of segfaulting.

    Be aware, that the Zend installer put those values in, not me. So a buggy Zend installer is to blame :)

    Not solved, still happening :/

    But I think checking the Zend stuff is a good thing to check :)

    I've heard of issues when compiling using PHP's built in MySQL support, instead of using "Use System MySQL" when using easyapache...

    Anyone else recommend this?!

    Thanks
