------- Additional Comments From rpluem@apache.org  2006-03-06 23:04 -------
Many thanks for the update. It was very helpful. The problem seems to be caused
by the fact that apr_reslist_release does not notice "double releases" (see also
http://marc.theaimsgroup.com/?l=apr-dev&m=114168465029319&w=2).
I am checking now if this is a bug inside apr-util or inside the proxy code.
If it is a bug inside the proxy code, I need to implement additional measures to
prevent such "double releases" (apart from removing the unnecessary double calls
to ap_proxy_http_cleanup which you already mentioned). These additional measures
should help track down such issues faster in the future and prevent the server
from segfaulting in such situations. I'll keep you updated.
