10004 - Mozilla is unable to render very large forms (700K)

Status: VERIFIED DUPLICATE of bug 6048

(Core :: Layout, defect, P3)

Description

[robertson]

The company I work for has a very large web interface.  Many of the forms for
our site are over 700 kilobytes in size.  I have not been able to render any of
these largest forms in any mozilla version.  I have tried m3, m5-8.  m3 would
actually crash the X-Windows system on my computer when I tried.  m5-8 just
never render it, but take up all of the processor and memory attempting to.

I am running RedHat 6.0 with Linux kernel 2.2.10.  GTK+ 2.2.3.  I have a
p166-MMX and 64 meg ram.

These forms render with Netscape communicator on Macintosh, Linux, windows NT,
but not Windows 3.1/95/98.

If you want a copy of a form that will freeze Mozilla (they are nothing but
standard HTML).  Please email me at [e-mail]

Eric-- please dig into this to see where the problem is. It could be forms
related, or it may just be layout related.

I received a test form from Andy.  I agree with Jan, this is a dup of bug 6048.

I was able to view this form and scroll down it in today's Necko apprunner.
However, loading and laying out the page consumed 198M of memory and took 7
minutes to display.  This was on my Pentium II 266 Linux box (RH5.2 + Kernel
2.2.1-5) with 128 Megs of RAM and two 256Mb swap partitions.  I didn't
experience any crashes or X problems but bad things would have happened if I
didn't have this much swap space or patience.

Actually, it was only consuming 72Mb of memory, the 198Mb figure included shared
libraries, buffers, cache, ...
