The Ultimate Guide to High Availability with MariaDB

Possible dead lock (OLS) - Possible mariaDB issue

Hi,

I have a server with OpenLiteSpeed & MariaDB 11. Every now and then (multiple times per day) my website completely freezes for about 1 min, and openlitespeed reports:

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

I believe that mariaDB stops responding, because when this happens, htop reports much higher than usual mariaDB instances.

Any idea where to look for more information on this?

Thanks Alex
