I think because AIO feature (UseAIO 1 or 2 ) is not enabled by default so maybe any user still not used that ( in ver 1.8.0)
can you testing on your side sir , because i was test in 3 different machine and got same results

 

[Cold-Egg]

I have tested OLS v1.8.1+ Ubuntu 22.04 + libaio1 without issue. I'm going to test it on AlamaLinux and get back to you.

Still no issue on a clean setup.
May I know if those machines all have DirectAdmin installed? Could you share how you enable/disable the AIO mobile on your server?

yes @Cold-Egg i write configuration in /usr/local/lsws/conf/httpd-tuning.conf

useAIO 1

and then restart lsws , after one or two minutes if any website opening in browser and core dump will created


error from gdb like this

[Cold-Egg]

Thanks, I can reproduce it now (need to visit any site to trigger it), will forward the issue to the LiteSpeed team.

 

[Cold-Egg]

The issue has been addressed and will push it to the next release.

 

[ctrlaltdel]

hii @Cold-Egg glad to hear it will be fix in next release
thanks bro

 

[hp2]

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

 

[Cold-Egg]

It's a [New Feature] , https://openlitespeed.org/release-log/version-1-8-x/

 

[hp2]

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?

 

[Cold-Egg]

It's under the Server Configuration > Tuning > Static File Delivery Optimization

 

[hp2]

With DA servers, the GUI is read-only. It would be very helpful if you can update the directives here.
Thank you

 

[ctrlaltdel]

Today i try to update 1.8.1 version , in version update logs it says fix for AIO crash
but looks still crash anyway , many coredump file still created after update to 1.8.1
maybe need rechecking @Cold-Egg

thanks
