Opcache issue on Openlitespeed 1.8

[cytrus]

I have an Almalinux 9.5 VPS (4CPU 8GB RAM) with Openlitespeed 1.8.

If I enable opcache I get errors and the site either gets stuck on loading or I get a white screen. This happens with lsphp74, lsphp82 and lsphp83. There is only 1 site on the server where I'm trying to install WordPress.

The server logs have these messages:

"Fatal Error Unable to allocate shared memory segment of 201326592 bytes: mmap: Cannot allocate memory (12)"

"No request delivery notification has been received from LSAPI application, possible dead lock."

In all php versions if I disable opcache with "opcache.enable = 0" in "/usr/local/lsws/lsphp82/etc/php.d/10-opcache.ini" and restart the server all the errors go away and I can install WordPress normally.

I tried different opcache settings besides the default, but none seem to work. My php memory limit in all PHP versions is 512M.

I think I found the issue. I later installed WooCommerce and had memory issues again. It had nothing to do with opcache. In my virtual host -> External App -> Memory Soft Limit (bytes) and Memory Hard Limit (bytes), I had these values too low I guess. I raised them to 2047M and everything works fine now even with opcache enabled.

Glad to know you have managed to fix the issue. You can also consider setting an empty value or 0 to not limit the PHP process.
