Решение - поднять лимит IOTimeout (локация конфига для CentOS 7):

# vi /etc/httpd/conf.d/fcgid.conf
FcgidIOTimeout 300
# systemctl restart httpd

IOTimeout - максимальный период, таймаут в секундах, который модуль будет ждать при попытке чтения или записи в FastCGI приложение.

Из документации Apache по mod_fcgid:

This is the maximum period of time the module will wait while trying to read from or write to a FastCGI application.
Note
The FastCGI application must begin generating the response within this period of time. Increase this directive as necessary to handle applications which take a relatively long period of time to respond.
