Cannot initialize zend_mm storage [win32]

can any one help me

Currently i'm doing load testing for our web servers with ab.exe tools which is comes with build in apache.

I'm getting error message in apache log file and error says :

Cannot initialize zend_mm storage [win32]

here is my steps to test the load

C:\apache2\bin>ab -c 100 -n 100 http://IPADDRESS/

-c 100 means ==> 100 concurrent users
-n 100 means ==> 100 concurrent transactions

My setup :

1. Apache 2.2.17 as a handler
2. PHP 5.2.17 as a thread safe

our application will not support the Apache as a Cgi/FastCgi and PHP as a Non-Thread Safe.

It's urgent

Thanks,

I suspect you're running Apache 32 bit and the machine cannot take the number of concurrent requests your attempting to send it with 'ab'. Switching to 64 bit Apache will solve it - though this might not be the solution you're after.

Here is my H/W Specs

Windows Server 2008 R2 with 64Bit Edition
Apache 2.2.17 as a handler with 32Bit
PHP 5.2.17 as Thread-Safe

Ok. I will try to download and install Apache with 64Bit and then try to test load with AB.exe Tools.

Alternatively Is there any other option to load concurrent users with more than 100.

Thanks,
