Your sql server cannot deliver when its under full load. Switch the host or optimize your code.

makvanpor2000 and morse thanks .. I think i have to change hosting provider

[GiLL]

there are many things behind failing mysql connection lets say
it can be server over load or over sold
you or they (server provider) need optimize my.cnf file
it can be issue you have not optimize or indexes your mysql table
you may need to check your data base if there any large amount data ,check mysql tables Collocation set to A etc also check your site code

Your sql server has too much load in it.
Its best to do what you said, change hosts or upgrade.
