After so many of these errors the website main page only shows as an all-white page. The server can be pinged at this point and can be remoted into. Svcs Apache and MySQL are running. Used memory is 20% at this point. Restarting the server brings the website back online. It is a Joomla site v3.9.26. (I use 2 services that text my cellphone when the site is down, but neither have done so when the site is all-white. I wouldn't mind a knowledgeable suggestion to monitor this Joomla site of some tool/application/extension, specifically when the main page of the site is all-white preferably with an sms notif. option.)
Getting hundreds of these errors in error.log for Apache:
VirtualAlloc() failed: [0x00000008] Not enough storage is available to process this command.
VirtualFree() failed: [0x000001e7] Attempt to access invalid address.
I'm using Xammp v7.3.2 w/ Apache/2.4.38 (Win32) OpenSSL/1.1.1a PHP/7.3.2 on a Windows 2012 R2 server w/32GB of memory.
In php.ini: memory_limit=128MB when the problem occurred (which was twice, 5/17/21 and 5/19/21).
I have since changed it to 2048MB. The problem has not occurred, but it has been only 7 hours.
I'm wondering (from what I have read) if it is a memory leak. If it is, is it possible to see how much memory it (Apache/Joomla/PHP) is using at any given time? Does anyone think increasing the memory will solve the problem?
Any other suggestions (no changes have recently been made to the site or to the hardware/OS)?
