We are seeing this message repeated in mailbox.log.
2007-08-10 09:33:29,811 INFO [http-443-Processor97]  FileUploadServlet - Exceeded maximum upload size of 10485760 bytes: org.apache.commons.fileupload.FileUploadBase$SizeL imitExceededException: the request was rejected because it's size exceeds allowed range
355 times since the log rotated at midnight to be exact.
We are also seeing enormous https traffic from a remote site, which has generated signficant excess bandwidth charges over the last few weeks. Here in Australia, bandwidth is charged per Mb.
I've just locked out all the users at the remote site and the bandwidth has dropped off. I am wondering whether perhaps a user has tried to send a really large email via the outlook connector, and then the outlook connector uploads 10Mb, gets a failure from the server and then retries?
It's only a theory, but something along these lines is sure chewing through our bandwidth.
Any thoughts on how to debug this are welcome!
