          Platform: PC
            Status: NEW

Windows debug file

We are currently running multiple web servers redirecting through
isapi_redirect to a single application server. We have frequent but intermitten
errors which result in the IIS workers processs w3wp crashing with the error
below (furthe information is in the debug file attached). Currenly we are using
version 1.2.30. I see a few bugs fixed for header lenght in 1.2.32 but none of
the fixes appear to directly reference this particular issue. As the bug is
intermittent (there have been gaps of in excess of 2 months between issues)
simply putting 1.2.32 on and waiting is not really an ideal situation. Does
anyone know if this issue has been addressed in 1.2.32
