I know it's a new feature, but as ctrlaltdel mentioned that he could enable / disable AIO, I thought there is a setting somewhere in the configuration? That's why I am asking how to enable it? :)

Just wondering: how to enable AIO? There is no KB, or something mentioned in the config. Thanks.

Yes, that's what I am wondering. By default they are 10000, and I think that are too much. I reduced to very small numbers, such as 5 and 10, and it seems still working fine. That's why I want to learn how to configure those numbers correctly. Thank you.

Wondering how to decide optimal numbers for those settings? Thanks.

No, I never touch those files. Not sure if it's related, but this OLS is installed with DirectAdmin.

In httpd-cgirlimit.conf, I set cgroups 2 which is disabled. However, in stderr.log, full of this kind of log: 2024-03-12 21:52:23.806729 Cgroups returning success file: /sys/fs/cgroup/systemd/user.slice/user-1039.slice/litespeed-exec.scope/cgroup.procs, pid: 3307480 2024-03-12 21:53:06.256329...

Following this KB, I don't have cgroups configured # ls /sys/fs/cgroup/cgroup.controllers ls: cannot access '/sys/fs/cgroup/cgroup.controllers': No such file or directory # cat /sys/fs/cgroup/cgroup.subtree_control cat: /sys/fs/cgroup/cgroup.subtree_control: No such file or directory However...

Install libxml2-devel and build php again.

How many days usually?

It doesn't matter at the limit is 200 or 40. If the server is under an attack, after restarting, the limit will be reached and the load goes up again immediately. But in this case, nothing. The limit is fine, the load is less than 1 after rebooting. That means something else, not the limit or...

This problem was just happening again. When it's happening, the load went up very fast. One second, the load went from 1 to 25, then 6x, 8x, 100+. I tried to killall lsphp, it didn't help. Another reboot brought everything back to normal, with the server load is 0.3. If it was an attack, after...

About CPU usage, which version of OLS are you using? They said there was a high CPU usage bug, which is fixed in version 1.17.19.2. If you are using 1.17.19 or 1.17.19.1, it might be the reason.

I am on DirectAdmin servers, don't think that I should update OLS manually. When are you pushing build 2 to github, please?

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...

Thanks for updating :)

I have an account using too much CPU. When using top command, I can see some processes from that account using CPU. Trying to use strace, but I always end up with the same error # strace -p 3992731 strace: Process 3992731 attached --- SIGPROF {si_signo=SIGPROF, si_code=SI_KERNEL} ---...

I don't know how to generate that error. I found them in the error log. Yes, the site is using Litespeed cache plugin for WordPress. I compared the time in the error log and the access log of that domain, but the access log at that time slot only shows requests to CSS, JS and JPG file. A...

Which information do you need including in the ticket?

The default server doesn't contain process ID. Then I modified the log format, adding %P (following this and this) to get process ID. On this server, I have CloudLinux. So, it has snapshot whenever an account is using over limitations. In lve-read-snapshot, there are PID, time when it's...

From version 1.7.19, I notice that message appearing in the OLS error_log. What does it mean, and why is it there? Thanks.
