Hi @Dolirow ,

You hit the limit somehow, please increase both number from 60 to e.g. 100

maxConns                60
env                     PHP_LSAPI_CHILDREN=60

Then restart the PHP by killall lsphp

Thanks!!

$ killall lsphp
lsphp: no process found

so I did:
systemctl restart lsws

still logs: No request delivery notification has been received from LSAPI application, possible dead lock.

Ok, thanks

and about that erro? (many of them)

Connection idle time too long: 31 while in state: 6 watching for event: 4, close!

Any solution to this problem @Cold-Egg I`ve got this same error.

For the PHP connection timeout, please try following this guide https://docs.litespeedtech.com/cp/cpanel/long-run-script/#easiest-solution to make PHP Without Timeout.

FWIW I think I solved it in my specific case. I'm a WP developer and I believe my refreshes of the Dashboard with "Disable cache" in the developer tools of Chrome might have overwhelmed the server with the lots of little scripts and uncached resources, as it's anything but serving static HTML pages, PHP is polled a lot. I checked on the OLS WebAdmin Console that the aforementioned message was plentiful in the log. After I made the following changes to Server Configuration > External App > lsphp, the notices in the error log changed to simply "[AdminPHP] add child process" followed by "Cmd from child: [extappkil...".

Max Connections: 1000

PHP_LSAPI_CHILDREN=35
LSAPI_AVOID_FORK=1
PHPRC=/usr/local/lsws/php/php.ini

The fork was a memory value which I have plenty of (It's an Ubuntu VM). The connections and children values were much lower. I believe while the OLS itself is responsive and in it I already bumped the connection counts, it's PHP itself that wasn't spawning enough child processes or hit connection limits and that made my dashboard hang a lot. It's kinda nerve-wracking when you want to work but the server is unresponsive, but you own the server, it's local, and you give it all the resources in the world.

Nothing of yours works, the errors will only be fixed when you set the Server configuration "CPU Affinity" from 0 to eg. 2
I have wasted some time tracking it down

Try checking your zlib setting in php.ini. setting compression on largely solved the deadlock issue for me. See the thread:
