I have an error that annoys me enormously because it makes me crash my website at times because the IOWAIT is too high. Here is the mistake I have:
CRITICAL on CPU_IOWAIT (Min:11.3 Mean:14.1 Max:15.7): bioset, bioset, acpi_thermal_pm
when the value is too high I have an ERR_TIMEOUT that appears on my site. Is it possible to fix the problem without changing the machine? Knowing that I have a dedicated server with only 1 website above but with 5 multiboutiques (Prestashop) Thank you for your help.
