VirtualAlloc() failed: [0x00000008] Not enough storage is available to process this command

Question

I have been facing this error quite a long time, My production environment is running Apache 2.4 and php7 on a windows 2008 R2 enterprise platform.

My error log is full of these lines VirtualAlloc() failed: [0x00000008] Not enough storage is available to process this command. VirtualFree() failed: [0x000001e7] Attempt to access invalid address

After some time it leads to a 500 error, and later I have to restart the server it works fine only for some time.

Please help me in resolving these issues I have tried to update the memory from php and wordpress end but still no help

Answer 1

Your project may not be setup on the appropriate architecture.

Is your PHP 32 bit? Check the PHP_INT_SIZE constant to find out.

print_r(PHP_INT_SIZE); # 4 == 32bit // 8 == 64bit

Windows Server 2008 R2 is an x64 operating system, so an x86 version of Apache +/- x86 PHP could be capping the memory you may have installed on your machine and are trying to allocate. You won't be able to allocate more than 2G on on x86 version.
