VirtualFree() failed: [0x000001e7] Attempt to access invalid

Postby sveny » 06. August 2018 14:25

Greetings,

we have a problem on our xampp setup which makes us sick. Our application breaks several times a day. Only a xampp restart does fix it for a moment. Unfortunately we are unable to fix this problem. This error comes:
Code: Select all
VirtualFree() failed: [0x000001e7] Attempt to access invalid address.
. We more than enough RAM unused when this error commes up. The application thread also does not hit the:
Code: Select all
memory_limit=3968M
The amount of memory which is unable to alocate is always changing. The amount of memory which is unable to alocate is small (1-50 MB) compared to the memory_limit.

Setup:

XAMPP: 3.2.2
PHP: 7.2.7
OS: Windows Server 2012 RC Standard x64
Server:Virtualized - Mware Virtual Plattform
Server-Hardware: 8x Intel Xeon E5-2667 v2 @ 3,30 GHz, 32GB RAM

Xampp for Windows is delivered in a 32bit flavour. In a 32bit environment each process cannot have more memory than 2GB (theoretically it could have 4GB, but this would not leave any space for system needs, therefore it is limited to 2GB).

Due to this fact, it is totally useless to assign such a memory limit as you did:

Code: Select all
memory_limit=3968M


Probably PHP will convert this invalid setting to any valid number, but i cannot tell which limit finally will be used. Anyway, this is useless and you *should* apply a limit beyond 2GB (i.e. 2048M or 2000M, i dont know if conversion is based dual or decimal). In any case, to apply a proper value for memory_limit, i would try a number a little smaller than 2000, just be save, For example:

Code: Select all
memory_limit=1996M


Restart Apache and try again.

If this also fails, obviously your Application needs to much memory, then you have to switch to a 64bit installation. Xampp does not support 64bit on Windows, you should switch over to Linux in that case, or use another stack than Xampp.

@Nobbie,

thanks for you answer. Unfortunately, setting memory_limit=1996M did not fix the problem.

Do you have any other ideas how to fix it? Please let me know if you guys additional information for reproducing.
