Comment 40 for bug 20765

mseele (michael), can you attach an http log as duncan did? Cite the URL you use to test. Instructions at http://www.mozilla.org/projects/netlib/http/http-debugging.html - duncan used:
set NSPR_LOG_MODULES=nsHttp:5,nsSocketTransport:5,nsHostResolver:5

Question - do you see the same behavior if you paste the URL in a new browser window immediately after starting FF? instead of opening through a tab or a link from another page?

Duncan, unfortunately the URL you used to test no longer works.

Alexsey doesn't say if this started immediately upon opening. What you describe in bug 233872 develops over time and is related to a combination of flash, garbage collection and huge memory usage that increase with time - well described in flash bugs. This bug is described as happening as soon as FF is opened.

Bug 40988 is about the creation and destruction of certain java data structures. My guess is not related to this bug. Perhaps to Alexsey's - but we don't have any URLs form alexsey to test.
