Is antivirus being used? In one case I remember having to increase some setting 
for ClamAV to allow large file uploads.

Subject: [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
org.apache.commons.fileupload.FileUploadException: Processing of 
multipart/form-data request failed. Stream ended unexpectedly


       at org.sakaiproject.util.RequestFilter.doFilter(RequestFilter.java:556)
