No problem.

Was it under some kind of attack or PHP loop, or simply it's a high-traffic site? For high-traffic site, maybe you can implement LSCache to reduce the PHP load and process number.

I am not sure about DA, but cPanel does not support OS upgrades, they recommend you to set up a new server, and then transfer the data. You might want to search DA docs if they support it or not. Your PHP packages are built on Ubuntu 20.04, it might not work with Ubuntu 22.04 even if it's 8.1.

When the issue happens again, please share the output with this command "ps aux | grep php", if you hit the PHP maximum/children limit, try "killall lsphp" and you should be able to log in to WordPress. You can also empty the value of Memory Soft Limit/Memory Hard Limit /Process Soft Limit...

OpenLiteSpeed supports Server Name Indication (SNI), allowing users to set SSL certificates at the virtual host level. See https://docs.openlitespeed.org/configuration#set-up-ssl-for-virtual-hosts for more information.

It seems working for me. https://wkb.computerhuys.nl/ returns "Hello New World! From OpenLiteSpeed NodeJS".

I did a quick test, with/without LSCache rules, and with/without custom cache rules, but no luck. If it's still happening, could you create a ticket to support@litespeedtech.com with this forum post appended for further checking?

Thanks for the report. May I know the cache entries you reported? I tried the default LSCache settings but it works fine with OLS v1.7.19. May I also ask if you see any similar errors (pCache is NULL, pInfo is 0x57e58c8, pReq is 0x57e5248, pPath is (nil).) in the error log...

Like, how to generate that error, by visiting a specific page or any page? Does that error kee showing? Is that page served by the cache?

Hi @hp2 and @sbmg18 , I tried a lot but no success to reproduce the issue. If it's still happening, could you create a ticket to support@litespeedtech.com for further check?

If the duplicate socket causes it, remove it with the following command, then restarting LSWS. rm -rf /tmp/lshttpd/* systemctl restart lsws If it does not work, the issue is something else. Maybe hit the PHP maximum limit, PHP code looping ..etc/ Let us know how it goes.

I will check on that and update here, thanks for the report.

No problem.

I am not familiar with NodeJS, can you help to provide any code that we can reproduce and debug?

Sure you can. 1. Create a new VH with the domain you want 2. Apply SSL for it and set it on the virtual host level 3. Setup a web server external application(https://docs.openlitespeed.org/docs/advanced/proxy#setting-up-openlitespeed-as-a-reverse-proxy) extprocessor webadmin { type...

I still can't reproduce the issue on my test site, if possible, please raise a ticket to support@litespeedtech.com with the forum post link appended for further support.

You can check the config file via SSH console if you prefer, e.g. /usr/local/lsws/conf/httpd_config.conf "If I use the normal php handler via Apache, it seems to download it". I'm a little bit confused, so, apache is loading fine, but it fails if OLS is in the front? Is that correct?

It seems your site has Ezoic cdn cache enabled, multiple full-page caches would cause such a display issue. Please consider using only one cache system at a time. If you want to use CDN cache, you might want to try QUIC Cloud CDN, which is fully compatible with LSCache.

For LSWS, the expiration value in the .htaccess file has higher permission than the web console. The expiration field in the web console will be applied if there's no expiration value in the .htaccess. Hope it's clear now.
