[Deploying Sakai] bigIP f5 issue

a client of ours is experiencing the following intermittent error when
uploading a file to Resources: HTTP Status 501 - Method 240776-- GET is not
defined in RFC 2068 and is not supported by the Servlet API

SSL is in place and the F5 passes back regular http traffic to tomcat.
Smaller files are usually ok, while larger ones seem to have trouble.  I
don't have data on what 'small' or 'large' is.

I don't have any administrative experience with this, can anyone offer any
ideas as the the possible issue here and/or share any gotchas around the
typical configuration that are unique for Sakai?

here's the stack trace snippet from tomcat:

2010-10-07 13:01:23,089  INFO http-8080-Processor42
org.sakaiproject.util.RequestFilter - Unexpected exception in upload parsing
