If you look 3 lines above the line with the writev for HTTP/1.1 200 OK you
will find that for the nginx_strace.26 log file (which failed with File is
too big) the recvfrom says that "X-Powered-By: PHP/7.4.26\r\nServer:
RainLoop\r\n" whereas in the nginx_strace.25 (which worked) There is no
"X-Powered-By: PHP/7.4.26\r\n", just the "Server:RainLoop\r\n"
