ERR_CONTENT_LENGTH_MISMATCH while loading js files on tomcat server

Configuration:

Issue: When the war file is deployed on tomcat, it gets exploded properly and the web portal works fine. Machine is idle for over 12 hours.

I access tomcat page: works fine. Even the manager page opens fine.
I launch my webportal, it does not load. Error: GET http://:8080/webportal/client/libs/jquery/jquery-ui-1.9.2.min.js net::ERR_CONTENT_LENGTH_MISMATCH 10.211.106.184/:63 I get this error for various other js files as well.

What i have tried:

Not an issue with memory since sufficient memory is available.
Tried to open the .js file in another tab, the page keeps loading for a long time and then stops loading. The file is not fully downloaded. Hence the content mismatch issue.
Access to the same url from the local CentOS box using wget works but access from browser on remote box does not
Once static file is accessed on appliance using vi editor (not saved only accessed), downloads from browser start working

Question:

What could possibly be an issue here? Is there any compatibility issue with tomcat and CentOS.
Note again that immediately after deployment everything works fine. Webportal does not work only after a few (>12 approx) hours of inactivity.

Solution

In conf/server.xml config file in apache tomcat folder set the "usesendfile" attribute to "false" as shown below:-

<Connector port="8080" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" URIEncoding="UTF-8"  **useSendfile="false"**/>
