    WAMP - Apache crashing issue while be crawled.

    I've been trying to track this problem down since last year and have finally pin pointed the problem to Xenforo. Now before you shoot me down in flames here me out. I've been suffering with random crashes in apache for a very long time and been looking closely towards a server problem but this is no longer the case. I did 3 crawl tests on the same server with the same configuration options using the same database. I used a package called Netsparker (Crawl only settings) and came up with some interesting results. I also have a VB and Flash blog installation on the server which i tested very extensively and they completed the craw test with no crashes within the apache log. However when i did the test on Xenforo the server keeps restarting with a 255 restart. I'm still unable to track down the problem URL's that's cause the crash. This is not just a local problem but an external too. I have tested the new 1.1.0 b4 and does far better then 1.0.4 but still crashes.

    Windows 7 pro 32Bit SP1
    Wamp Developer Pro V4.0.3.3



    Also there is a 500 server error created with these URL's


    Only happens on the Xenforo installation for some resion.

    ^ heres your problem, windows :D

    The error pertaining to the php module would be my first guess, have you tried using a different php version?

    I really don't wan't to give up my Wamp :(

    Yes i have tried lots of different PHP, Apache, SQL versions. This has been with me since the beta days of Xenforo i was unable to track down what was happening till a few days ago. VB and my flash blog works wonderful.

    Unfortunately, the errors you provide are vague, a 0xc000000000005 releates to an access violation error, the best I could suggest is running an indepth memtest to see if you may have a fault there.

    Otherwise, come join the linux brigade ;)

    There is no memory faults on the server and if this was the case wouldn't the other 2 sites crash also :whistle: . Unfortunately switching to Linux is not a option for me. Plus i know nothing about Linux anyway :cry:.

    You never know, I know your logic but ive seen situations before than defy that logic so pushing the boat out sometimes helps.

    Either way, you will probably need to get a window server expert to have a look for you, though have you tried just doing a backup and complete rebuild of the server?

    Yes server was completely rebuilt Sep 8 2011 with the OS and Wamp. I have been testing this on my test installion also (another computer) and still does this with a completely clean installion of Xenforo and database. :(

    I use WAMP and it runs perfect for me with XenForo, but then I'm on Windows XP. Does WampServer even work on Windows 7?

    You also have to make sure you don't have IIS (ISS), not sure which it's called? Running in the background that comes with most "PRO" versions of Windows. WampServer is also very funny depending on which version you download and use. The best version I found was WampServer 2.0 (first release) made. I've tested them all and some will give you errors in logs.

    The version I use doesn't give any errror logs after a lot of trial and error testing out each version of Wamp.

    Best version is this one:

    WampServer 2.0
    PHP 5.2.6
    Apache 2.2.8
    MySQL 5.0.51b

    It might be an older version, but it's the best one.

    So much trouble for something so simple. If you had tried googling for Apache php5ts.dll it would have told you that this is a very common error with WAMP installations on windows servers. The issue is caused by when php is used as a compiled Apache module. Apache crashes because the php module does something which the operating system, windows, does not allow it to do and it terminates the entire process, meaning Apache.

    In most cases the solution would be to use the latest WAMP / XAMPP versions. It's something very difficult to pinpoint to the exact fault though, unless you happen to be able to debug windows dlls.

    And for the record it's not a XF error. It will happen with even a simple phpinfo() file for servers where the fault happens.

    Thanks mrGTB i'll see if i can intergrate it some how into the software.

    Thanks for the insight sadikb (y) . I did call phpinfo() and produced no system errors. I can understand what every one is saying but i still wish to know why Xenforo is crashing Wamp and Vbulletin is not. If this was a total Wamp problem would they not both be doing it.

    My suggestion would be to try an alternate LAMP setup. Install Xampp and see if the same error occurs.

    Is not as easy as that. I have 3 domains running on my existing Wamp installation. It's not something i can just try if you know what i mean. Everything on my current software is different to the rest. Dir's, Config files, everything really..... The idea was to make it easy to maintain and repair if required. I haven't got the technical background to configure such a setup from scratch.

    I've sent a email off to the software developers to see if a downgrade to Wamp is possiable.

    So if this is the case by changing Apache, MySQL and PHP to the versions mrGTB said should correct the problem yes?

    Guess i can't as they need to be VC9 complied to work. :cry:
