recently, we often have more than 502 cases online during the evening peak. After inquiry, there are indeed many full logs at the time of alarm, but we are a little confused after seeing the slow logs, as shown in figure 
, slow logs are all in the 322 lines of code in composer"s classloader.php file, and this line of code just calls a function:
/**
* Scope isolated include.
*
* Prevents access to $this/self from included files.
*/
function includeFile($file)
{
include $file;
}so now I am a little confused, and we have deployed more than 10 sets online in parallel, and only 3 of them have this situation. The server load, ah, and so on are all normal, and there are no special cases such as soaring. I don"t know if you"ve ever met, ask for advice from the gods, and what kind of investigation ideas do you have?
