Yes, Just Host database server sucks. Why? I am a WordPress user for more than 4 years. I faced “WordPress database error Can’t create/write to file ‘/tmp/#sql_39d0_1.MYI’ (Errcode: 28)” for the first time when using Just Host shared web hosting. What is error 28 meant? Based on Linux, error 28 == no space left on device. Come on, this is what Just Host called ~ Unlimited GB’s of Space??? Does Just Host support team do their job by monitoring server disk space? I doubt that.
The outcome after getting this error 28. WordPress categories and tags are gone. And even worst sometimes, all the posts are gone because database server cannot write anymore on the tmp folder. So basically, your blog are down for good. How frequent do I get this? Once in a week if I am lucky. Else even worst ~ daily…
By the way, you will get this kind of error when all the post are gone ~ “WordPress database error Table ‘./YourBlog/wp_posts’ is marked as crashed and last (automatic?) repair failed for query SELECT wp_posts.* FROM wp_posts…”
