           Summary: Large form post data causes unstoppable memory growth
                    and crash
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Macintosh
               URL: http://chrisbosco.com/proto/safari/
        OS/Version: Mac OS X 10.7
            Status: UNCONFIRMED
          Severity: Major
          Priority: P4

        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: matt.slocum at ymail.com


The example above is not from me, but from someone else that is also experiencing the same problem http://chrisbosco.com/proto/safari/

An HTML5 Canvas element creates very large data strings when submitting in a form using mycanvas.toDataURL(). Other browsers submit large form post data properly, but Mac Safari, Mac Chrome, iOS Safari (iPhone & iPad) causes huge memory growth. Post data around 500KB makes the browser spike to >600MB of memory and become completely unresponsive (iOS browsers crash). The server does receive the connection and some of the data.
