Recurring Crash of Confluence

[Jeff Franzke]

Hello, 

I have just installed Confluence on a new virtual machine (Windows Server 2016) and the confluence seems to always crash after 24 hours. 

I'am using MySQL as the database. 

What could be the issue?

Thanks, 

Jeff

What does "crash" mean?  What do you see on screen? 

More importantly, what does the log file say the problem is?

I'm afraid one snippet of log does not really tell us anything.  Could you describe the "crash" in detail as well?  What do you get on screen?  What do the application logs say when this crash happens?

I tried pasting the whole command output, but the form did not allow it. 

I get website is unreachable. 

In task manager I see java and tomcat running, but only at 0% with 1766MB Used

The webserver just dies and then you cannot access the web application. Only 1 user is using for now..
