A common reason for Alfresco to stop responding is when Java is out of memory and the services or server will require a reboot.
On the Alfresco server the Tomcat service and Postgres service can also be running although Mosaic cannot upload or download documents to Alfresco, this is also another symptom.
Complete the following checks
RDP to the Alfresco server
Open Services on the server.
Confirm that the services alfrescoPostgreSQL and alfrescoTomcat are running.
Confirm that the server has not run out of disk space.
Try accessing the Alfresco web front end from a browser on the server using the URL: http://127.0.0.1:8080/share/page/
If the page fails to load the login page this is also a sign of a problem.
Check the logs for errors
Alfresco logs can be found in the following folders:
<install drive>:\Alfresco
<install drive>:\Alfresco\tomcat\logs
Possible Resolutions
If the server has run out of disk space, try freeing some space or request additional disk space from Access Cloud services.
If either service is not running, try starting them and see if this resolves the issue.
If they are both already running, try stopping them both and then starting them both.
If this does not resolve the issue, try restarting the Windows server.
Increase the JVM for Tomcat
If the logs indicate that Java / Tomcat is out of memory you can try allocating more memory to Tomcat.
RDP to the Alfresco server.
Open a command prompt.
Change the folder path to cd <install drive>:\Alfresco\tomcat\bin
Enter the following tomcat7w.exe //ES//alfrescoTomcat and press enter. This should launch the alfrescoTomcat properties dialog. below:
Select the Java tab.
Increase the value of the field Maximum memory pool. Subject to available memory on the server.
Restart the alfrescoTomcat service in Windows Services.
