Description:
------------
While I run APC Cache in WAMP environment, I tried to execute a PHP page in command line but its throwing the following error :

[apc-error] apc_shm_create: shmget(0,
31457280,658) failed: No such file or directory. It is possible that the
chosen
egment size is higher than the operation system allows. Linux has
usually a default limit of 32MB per segment.

Event if I simply type php.exe then enter it gives the error. No idea where the problem, I went through some of the Rasmus comments says "Enable MMAP" but in windows its already precompiled state DLL, so can you suggest me how to fix this problem?

Reproduce code:
---------------
c:\wamp\bin\php\php test.php

Actual result:
--------------
[apc-error] apc_shm_create: shmget(0,
31457280,658) failed: No such file or directory. It is possible that the
chosen
egment size is higher than the operation system allows. Linux has
usually a default limit of 32MB per segment.

I am also experiencing a similar issue. It appears from a separate blog post I found that if you have Apache running on the same machine, and attempt to run a PHP script with APC enabled, then you will receive this error.

If I then turn off Apache (2.2 in my case), on Windows XP, then run the PHP script, everything works fine.

However, this doesn't really seem viable. What if I want to run a server on a machine, and also have PHP script running on that same box.......I will get this error.

Is anyone looking into this, or do they have a solution?

Thanks.

What is your php.ini settings for apc?

I got same error with this APC settings:

[apc]
extension=php_apc.dll
apc.enabled = On
apc.enable_cli = On

WinXP, Apache 2.2 VC9, PHP 5.3.1 RC 1 VC9, APC 3.1.3p1
(I got same error with 5.2 VC6 and older version of APC)

Same problem here.

Server 2003, Apache 2.2.14 VC9, PHP 5.3.1 VC9 (both TS and 
NTS), APC 3.1 VC9 (both TS and NTS) from 
http://downloads.php.net/pierre/ (dated: 20091026)

When running PHP as a module in apache, web pages come up 
blank, if I run php.exe (while apache is still running) I receive 

[apc-error] apc_shm_create: shmget(0,
31457280,658) failed: No such file or directory. It is 
possible that
the
chosen
egment size is higher than the operation system allows. 
Linux has
usually a default limit of 32MB per segment.


If i stop apache, I can successfully run php.exe.... but 
that doesnt help me too much :)

Can you verify that your system is not running low on/ or out of memory?  Perhaps this could be a failure due to the system being unable to allocate memory for the shared memory segment.

System has 1.3GB of physical ram not in use. Ive tried 
everything from setting the shm size to 1M to forcing 
apache/php to run as admin w/ full rights. Its quite awkward.

It appears that APC is running just fine when I load php using  
fcgi - load tests & phpinfo() confirm its loaded.

Only fails when loading php as a module or when trying to run 
cli when fcgi is running (im assuming this is because of a 
sharing violation of some sort?)

Same problem on Wamp (PHP 5.3.7 - Apache 2.2.11)

Here is the command line code :
php -d apc.enable_cli=1 -r "apc_clear_cache();"

I had the same problem with WAMP 2.0 running on Windows. It turns out that php.exe 
under WAMP folder is loading different php.ini file. 

You have to run "php -i | more" to find the location of the php.ini file ( loaded 
configuration file ). After that you have to enable the apc manually by adding 
extension=php_apc.dll and the apc settings ( read the comments above ).

I hope that helps...

According to <https://bugs.php.net/69618>, APC support has been
discontinued in favor of OPcache, APCu, the session upload
progress API and WinCache. Therefore this issue won't get fixed.
