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?

[2009-10-10 10:11 UTC] kukulich at kukulich dot cz

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)

apc.enable_cli = On

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.

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.

[2009-12-16 10:17 UTC] spoon at nexdot dot net

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();"

[2013-07-03 04:22 UTC] rudylee1988 at gmail dot com

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.
