From the releases page, I see you just pushed new files 2 days ago. But instead of creating a new version 1.7.19.1, it seems you updated to the version 1.7.19, which was released 3 weeks ago? In the change log, there is a bug fix for high CPU usage. Is this bug appearing in 1.7.19? Or in older...

I just upgraded my OLS from 1.7.18.1 to 1.7.19, and noticed that I cannot download files completely. The files are downloadable PDF files in a WooCommerce store. It was working fine before. But now, when customers click to download links, it started at 10+ MB/s then immediately reduced to 0. So...

Which one is giving better performance? For example, 1 worker with 200 maxConns or 4 workers with 50 maxConns? How to monitor the performance in each case? Thanks.

My server is suddenly having very high load, more than 250, while usually, it's less than 1. A lot of connections coming in. And ps command shows defunct php root 35253 0.0 0.0 40908 6536 ? S 20:50 0:02 openlitespeed (lshttpd - main) root 35254 0.0 0.0 30704 2872 ...

So, the customer has a domain domain1.com, hosting on server A. The domain1.com is redirecting 301 to domain2.com, running on server B. When I was running nginx apache, alias such as domain1.com/webmail was working fine. It's just directed to the real URL domain1.com/roundcube When I converted...
