Hi David,

so far, i could not recreate the problem. By reading the backtrace, the 
problem
seems to be that the connection has no ns_set for the header fields. 
This is strange,
since every ConnRun() sets these fields, an these are cleared after the 
ConnRun(),
while the problem happens within ConnRun().
So i wonder, how connPtr->headers can be lost. I see from the backtrace, 
that the issue
happens in a preauth filter named  "filter_dos_check". Can it be, that 
this filter somehow
causes a cleanup of the connection? I can't see in the code, where this 
might happen.

For the time being, i've protected the crashing function call with test 
for the
headers and added a debug line for the error.log. So, the crash at this
very situation should disappear.  But probably, the function should not
be called in such situations at all, there might be as well other places,
that depend on the assumption, that the ns_set for the header exists 
during the run.

Do you see anything in your filter code related with this?
