apache httpd is restarting once a day with error AH00428: Parent: child process xxxxx exited with status 3221225477 -- Restarting

We have Apache/2.4.34 (Win32) OpenSSL/1.0.2o configuration for one of our user environment. The apache process exits once daily and restarts automatically. Things are working fine after the restart. They have applied patch(SSL). Could it be a reason for restart? IS there any compatibility issues with Apache/2.4.34 (Win32) OpenSSL/1.0.2o configuration

And The apache process increases memory to 1.5G in less than a day, around 12 midnight and its releasing automatically, then some times its restarting immediately, and some times its running fine for few hours and then its restarting with exit code 3221225477 .
My doubt is how to check why its increasing memory and how to find reason for restarting?

normally error log is not reporting any error except AH00428: Parent: child process xxxxx exited with status 3221225477 -- Restarting.

And access log seems fine. We did not see any log messages at the time of restart in access.log For one or two days, we have observed below errors in error.log around midnight, but apache did not restart immediately after those errors.

They don't have anything scheduled at midnight, they have cron job which will run daily at 4'o clock, this cron job also restart apache every day. Sorry for the long post. Any help would be greatly appreciated.


This problem often happens in Windows because of smaller Apache’s default stack size. And it usually happens when working with php code that allocates a lot of stacks.

To solve this issue, add the following at the end of apache config file, httpd.conf

<IfModule mpm_winnt_module>
    ThreadStackSize 8888888
</IfModule>
