IIS 10 and Wordpress getting crashes

Question

User-1170642558 posted

We have a multiple web server configuration for Wordpress.   There are two servers.   Getting a crash on one of the web servers which is bringing the site down.    It happened again a couple days ago.    This is what I am seeing in the error log.    The other web server doesn't seem to have this problem, but should have the same config.    Not sure how to resolve?

Sounds like a crash (access violation) caused by 2.0.0.8 version of php_wincache.dll when running on PHP 7.3.7.

You might report to DropPhone , with a reproducible sample,

Still getting this issue on the one web server so bumping this thread.    It will crash maybe once a week then I need to recycle the App Pool.    I added a post to the other thread you sent but didn't get a reply.

Looking around it sounds like I might need to change some of the settings, particularly to FastCGI,    These are my settings... any recommendations on these?    Also I changed the AppPool to recycle every 240 minutes.

PHP 7.3.7 ?

Did you set the Environment Variables Collection setting for PHP_FCGI_MAX_REQUESTS to the same value as instance MaxRequests ? Interesting that you have it monitoring php.ini without a path shown. That's not what I see on ours. Do you have a job running in php that takes 6 minutes, like a huge wordpress backup job or something? If not that's excessive.

I am getting the exact same error.

Windows Server 2019.

PHP 7.4.11

When this crashes, it knocks the website offline for several minutes.
