Unfortunately, tomcat is not responding to *any* requests until the upload completes. After the upload, everything is fine.
We've reviewed our tomcat settings, and have not found anything that has helped either--I was thinking that we might only be using one thread due to some mistaken configuration, but that is not the case. We see the CPU usage climb up to about 20% when dealing with large file uploads, but it is no where near maxing our cpu usage on our dual xeons. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of James Carman Sent: Wednesday, October 25, 2006 1:07 PM To: Jakarta Commons Users List; [EMAIL PROTECTED] Subject: Re: fileupload makes tomcat 5.5 unresponsive for other users Are you saying that Tomcat isn't responding to any other of the same type of requests (other file uploads) or it's not responding to *any* requests at all (even requests to other webapps within the same instance)?
