Apache2/Flask：从守护进程收到的截断或过大的响应标头

Question

我正在运行一个 flask 站点，我时不时会收到此错误。

[Tue Feb 16 10:44:19.574903 2021] [wsgi:error] [pid 334775:tid 140550036739840] [client 37.120.131.220:34692] Truncated or oversized response headers received from daemon process 'myapp': /var/www/html/myapp/app.wsgi

My.conf 文件是这样的：

WSGIApplicationGroup %{GLOBAL}
WSGIRestrictEmbedded On

<VirtualHost *:80>
    ServerName myapp.com
    ServerAlias www.myapp.com

    WSGIDaemonProcess myapp threads=5
    WSGIScriptAlias / /var/www/html/myapp/app.wsgi

    <Directory /var/www/html/myapp>
        WSGIProcessGroup myapp
        WSGIApplicationGroup myapp
        Require all granted
    </Directory>
RewriteEngine off
RewriteCond %{SERVER_NAME} =myapp.com [OR]
RewriteCond %{SERVER_NAME} =www.myapp.com
RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [END,NE,R=permanent]
</VirtualHost>

<VirtualHost *:443>
    ServerName myapp.com
    ServerAlias www.myapp.com

    WSGIScriptAlias / /var/www/html/myapp/app.wsgi
 
    <Directory /var/www/html/myapp>
        WSGIProcessGroup myapp
        WSGIApplicationGroup myapp
        Require all granted
    </Directory>
Include /etc/letsencrypt/options-ssl-apache.conf
SSLCertificateFile /etc/letsencrypt/live/myapp.com/fullchain.pem
SSLCertificateKeyFile /etc/letsencrypt/live/myapp.com/privkey.pem
</VirtualHost>

我的配置文件中是否有任何错误并导致此问题？
