It is good to see some analysis on this issue. Here is link BTW:


A couple questions:

1) This seems to happen only with Apache 2.2 and not 2.0. Is there
any explanation for that supported by your analysis?

2) It seems like many of the people, at least on Windows, can
reproduce this problem quickly. Could this just be due to running
requests which create/destroy a lot of memory?

3) Any reason more Windows users would see this than Linux? Maybe
more Windows SVN users use Apache 2.2 than on Linux?
