           Summary: Problems serving large (50k+) static images on linux
           Product: Tomcat 5
           Version: 5.5.12
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: major
          Priority: P2
         Component: Catalina
        AssignedTo: tomcat-dev@jakarta.apache.org
        ReportedBy: pcasey@earthlink.net


I have a web app that spits out dynamic pages that include within them links to
static icons and whatnot. A typical <img> looks like:

<img src="./img/help/newsurvey.gif" />

These all work perfectly on Tomcat 5.5.9 on Windows XP.

When I move the war over to my linux box with Tomcat 5.5.12, however, all the
<img> tags that point to images over about 50k break. I don't get a broken link,
I don't get a half an image, I just get ... nothing.

When I look in catalina.out, I see what I think is the error message, but I
can't figure out the cause.

Again, small images server just fine. Big ones cause errors, but only when
references via links as I described.

Also noteworthy is that Tomcat appears unable to serve the image even if I
navigate to it via the url directly e.g. typing:

http://p500:9090/Corinna/img/help/navigatemain.png

Results in the same error.

The error I get the *first* time I go after the resource.
