Topic: Turned on JIT and get crashes in php5ts.dll

[Simbiat]

I noticed my apache crashing frequently (I get a "JIT disabled" message).
I turned on JIT in Visual Studio 212 and here's what I get:


Both apache and PHP are x64 now, but the same happened on x86 builds as well. In every case builds were downloaded from here.
Any idea, what may be causing this? Let me know if any extra information is required.

I know JIT with PCRE.

Where do you see the message "JIT disabled" ?

Please tell where you set JIT on in Visual Studio 2012 ? You build PHP and/or Apache with JIT ?

[James Blond]

Did you disable JIT in php.ini ?

[Simbiat]

JIT is enabled both in VS2012 and PHP at the moment, but the above screen is the maximum I am able to get. And not, I did not compile anything. Both Apache and PHP were downloaded from the lounge.

[James Blond]

Do you load any extensions in php.ini? If yes please try without any.

[Simbiat]

if you mean PHP extensions - tried that. does not seem to have any affect at all

[James Blond]

Can you please post the apache error log from the crash?

Your apache version?
Your PHP version?

[Simbiat]

Log - https://www.mediafire.com/?5uolxrt91a83q53

Apache v2.4.7
PHP 5.5.6
Both x64, both downloaded from apachelounge.com. The log is for today and I had at least 3 crashes like that today

[James Blond]

Well I see some issues that you need to fix.

[Simbiat]

I had such version notices for mod_security before (even before the crash issue appeared) and it never affected anything...

Why should I setup SSLSessionCache if I do not use HTTPS?..

I seem not able to find precompiled mod_fcgid for Windows...

[James Blond]

fcgid is on the download page. http://www.apachelounge.com/download/


SSL seems to be loaded in your server. At least in your log the server complains about it.

[Simbiat]

I also forgot to mention, that it crashes on Windows Start-up. Like it can't start-up until ~2 minutes after windows turns on...

[Simbiat]

Also did not mention, that when the error appears, server continues to work, unless I press OK...

[James Blond]

I think the VS debugger causes that problem. I had that once.

[Simbiat]

what do you mean? I have disabled by default anyway... Normally I get error message like "unhandled exception, bla-bla-bla, JIT is disabled, enable it, bla-bla-bla"...

[Simbiat]

with fcgid I get constat errors like "Unhandled exception at 0x0000000076F329EB (ntdll.dll) in php-cgi.exe: 0xC0000005: Access violation writing location 0x00000000020D3B64."

In logs I see a lot of "mod_fcgid: get overlap result error" and "End of script output before headers"

[James Blond]

ok, at least you know nopw for sure that PHP causes the issue. You should try a very simple PHP script and see if the server crahses then. I would try the offical PHP binaries from windows.php.net

if a simple script crashes with the offical PHP binaries then your system is broken.

[Simbiat]

seems like same thing happens on official binaries as well. Although, not like I have a "simple script to test on"... I just start my server and wait for the crash. How to determine what exactly is "broken" in my system?..

[James Blond]

broken system means that something is messed up and PHP will crash anyway. I would try on a second clean / new set up system.

I recommend to turn on the error debugging log in php.ini

display_startup_errors = On
log_errors = On
error_log = C:\Users\james\php_errors.log

Can you see a specific script or so in the apache logs before apache crashes?

[Simbiat]

Nothing in Apache at all... I made a clean install now... Waiting for a crash.
