Hi, I have 6 light wordpress websites in a single account. 5 of them is actually an ecommerce website, but not using woocommerce and having very minimal layout modification and function calls using foodpress theme. This is very light compared to woocommerce.
Ram usage from
smem -uk -s rss command is constantly above 1G for this account, and peaked on 1.9G on RSS and 1.5G on swap.
I also have a website on other virtualmin server with <100 visit per day using woocommerce, but with some wp-rocket and redis. It also used about 1.5G rss and swap.
Both VPS sometimes have memory exhausted, resulting in returning error 500 timed out on browser and sometimes Bind DNS killed.
I never have memory problem on cpanel with much higher traffic woocommerce websites, can somebody give me a pointer on what to look?
edit: add VPS details
