Tomcat File Upload Timeout

[squibobblepants]

Attempting to build and deploy a web-app through Tomcat is proving a problem.

I have tried building through an ant task, and through the manager area of Tomcat. Each time I get the same error (eventually):

-------

This has only been a problem since the start of the week, and has always worked before then. I am wondering what the possible cause/solution may be. The War file I am uploading is apporximately 15mb, but it is to my localhost so it really shouldn't be timing out. I have disabled my firewall and anti-virus, so these shouldn't be stopping it uploading.

Many thanks in advance for your responses.
