I'm using a mongo database link to a AngularJS/NodeJS website on an Amazon server with ubuntu 14.04.
Since 1 month, every 5 or 6 day my data are unreachable I can't connect to the website with mail/password. I need to shutdown the database and relaunch it to make it works. And all the data stored are lost.
I don't understand why and the logfile looks normal.
Here it's the full log when the bug appears

When I'm launching the database I use this command
sudo mongod --fork --logpath /var/log/mongod.log --dbpath /home/ubuntu/data/db
Is it because I'm using sudo for launching the database ? Maybe mongo need some permission in read/write for doing some things and he can't so the bug appears ?
My first thought was because the server was too small so I increase it from 8Go to 16Go but this change nothing and the bug appears yesterday

I have big scary problem with SQL Server 2022 in LXC containers on PVE.
SQL Server 2019 is working fine in same environment but SQL Server 2022 crashes after few months of working good. After crash it can't be restarted only solution I found is to reinstall the container.

Anyone can help to stable the mssql service on the vm.
Does your Ubuntu server have the firewall enabled? If so, it may be blocking port 1533, which is preventing the service from starting on that custom port.
You may want to look in /var/log/messages for additional information as well.

I run an apache2 webserver locally on a raspberry-pi with raspbian distro.
It worked without a problem until suddenly it can't be started anymore with
sudo /etc/init.d/apache2 start, which yields the following error:
[....] Starting apache2 (via systemctl): apache2.serviceJob for
apache2.service failed. See 'systemctl status apache2.service' and
'journalctl -xn' for details. failed!
Removing and reinstalling with apt-get doesn't solve it.systemctl status shows the following entries:

Unfortunately the apache error.log contains no useful information whatsoever. But if i run apache2 configtest I get a "File name too long" error.
Strangely even after formatting my sdcard and putting a fresh copy of the distribution image on it and reinstalling apache2 the error remains.
What can I do?
This is my program:
#include "fcgi_stdio.h"
#include <stdlib.h>
int main(){
while (FCGI_Accept() >= 0){
FCGI_printf("Content-Type:text/html\r\n\r\n");
FCGI_printf("<h1>Test</h1>\n");
}
return 0;
}
These are the options I added to the apache config for the virtual host I'm working with:
SetHandler fastcgi-script
Options +ExecCGI
I also have the following line in the same apache config file:
LoadModule fastcgi_module modules/mod_fastcgi.so
I followed directions at FastCGI script can't find libfcgi.so.0 in Apache 2.4.6 and mod_fastcgi to compile my program.
If I execute the compiled program directly, I receive the familiar "segmentation fault" on screen. When I try executing it via the server at http://127.0.0.1/a.out, I get an internal server error and the following in the error_log:

Its basically telling me that apache is attempting to start the program a few times but the program returns segmentation fault.
The result I was expecting was the word Test in bold in a web browser.
How do I fix my program to make it compatible with fast-cgi so that I can execute it via a web browser?
I don't want to resort to the slow CGI interface which is why I'm trying to use functions beginning with FCGI.
