php是否注意到对发送到nginx的数据大小的影响？

Question

i use nginx and php7.1-fpm.

In case when i have a bunch of notices in error log, at end i get in logs error and error 502:

*5 upstream sent too big header while reading response header from upstream

If i increase buffers size in nginx all works well.

If i remove custom buffer settings and checkout to branch with fixed notices, all works well too.

So my question - is notices influences to data size sending from php-fpm to nginx?

Answer 1

And now i understand that i see notices in nginx logs. So of course its influences.
