I'm trying grpc multiprocess example listed here on OSX -
https://github.com/grpc/grpc/tree/74bba2c90a4f4607674a01ec1c0b634708fea887/examples/python/multiprocessing

I do see multiple server processes started. However, on running the client, I see only one of the server PID logged in server logs. Sample logs below. I expected it to be spread across all the server processes. Am I missing something here?
[PID 19295] Determining primality of 1139
[PID 19295] Determining primality of 779
[PID 19295] Determining primality of 1709

[PID 19295] Determining primality of 2334
[PID 19295] Determining primality of 564
[PID 19295] Determining primality of 1494
This seems to be a problem with OSX. I tried this in Ubuntu and it works fine with all the server PIDs being used.

I have installed a WordPress site in AWS EC2 t3.micro on platform Linux/UNIX. The ec2 instance stops responding every few hours. That means if I try to call the website from the browser I get "This site can't be reached" message. The site starts to work again if I reboot the instance from the ec2 console. The inbound rules for HTTP and HTTPS set to 0.0.0.0/0. There is a number of website visitors. There is 4.2G available space on the EC2 instance. The latest error log entries are:

Could anyone please advise?
I am running the latest XAMPP and Wordpress on my Windows 10 machine, and everything has been working fine for more than a week. I run two websites under XAMPP/htdocs, web1 and web2. This morning Chrome said Connection Reset for web2.
localhost/dashboard loads the XAMPP page correctly.
localhost/web1 loads web1 correctly.
From this I conclude that XAMPP, Apache, WP, and MySql are all working correctly, for web1.
But for some reason Chrome and IE get Connection Reset errors on web2.
I can't log into the wp-admin screen on web2 either.
I've looked for solutions on the net, emptied browser caches, etc, and even did a 'netsh winsock reset' on the whole computer, but with no success.
I think it's something wrong with wordpress on website 2, because web1 works fine, right beside web2. Does anyone have any ideas on how to troubleshoot this? I may end up reinstalling wordpress and all my plugins, etc.
Here's my apache error log. Not sure if these errors are relevant, because they are in the log when everything was working fine, too.

I finally gave up, reinstalled wordpress, and imported an old backup of the site. I lost a tiny bit of work (my backup was recent), but in total it was far less work than trying to debug the failed site.
One of the biggest problems with a "Connection reset" error is that you can't easily interact with the site through a browser. Unless you know exactly what the problem is under the hood (I didn't know), and know exactly what system / wordpress files to change (I didn't know), debugging is impossible.
I'm answering this question and closing it so that others might benefit from my experience, and reinstall their own failed site before wasting too much time like I did.
I´ve got a problem with installing wordpress on centos 7.
I used this guide to install it cause I´m quite new to linux:
https://www.digitalocean.com/community/tutorials/how-to-install-wordpress-on-centos-7
I did everything step by step but it didn´t work. So I decided to reinstall my root server cause I wanted to have a new clean machine on which I could try it again. Then I used this guide to install it:
http://www.linuxveda.com/2015/09/15/install-wordpress-centos-7/
Same error as before..

Can anyone help me? Since now I´ve got nothing installed on the server except teamspeak 3. On my old root server (Hetzner Online) everything worked well but now it doesn´t...Any ideas of how to fix it? I already changed the permissions of all wordpress files but still the same error..
They key is
Permission denied
Check permissions of the folder and files where you are storaging your wordpress files, apache should be able to read them.
Site was working fine this morning and now just a white screen after about a 45 second load. Latency is super high and saw a huge spike in database requests before crash. Here is some info from the error log:

The fact that the "server reached MaxRequestWorkers setting" is a little alarming. I can't answer why that happens, but that might be the result of another problem.
If hitting the MaxRequestWorkers setting itself is not the RESULT of another problem but the problem itself, you can raise the "MaxRequestWorkers" ceiling in /etc/apache2/mods-available/mpm_worker.conf, then restart Apache.
I can access the actual wordpress site via WAMP's localhost route, but I cannot log into the admin/dashboard page of the wordpress site.
I think it is a problem with apache.
Can anybody help me?

More info:
The error is not a 404. Rather wordpress doesnt recognize my username/password.
final edit:
found a solution to my problem:
