I've installed Alfresco 4.2.b on an Ubuntu 11.10 server and made no customizations.
It it is running fine, but there are two problems: one that shows up in a log file and one that shows up in the system CPU usage.
Every 15 seconds, there are about 26 to 30 messages similar to the following written to /opt/alfresco-4.2.b/tomcat/logs/localhost_access_log.2012-11-05.txt:

The second problem is that after the tomcat server is started and finished initializing and is running idle, it consumes about 1% of the CPU - which seems normal. However, as soon as I log into Alfresco Share, the CPU usage jumps to 10% and stays there until I shut the server down. Logging out of the server and closing the web page has no effect on the CPU usage - it's still at 10%.
Is anyone else seeing these problems or know how to resolve them?
