Subject Re[2]: httpd-2.1.3-beta under a large DDOS attack ... not good.
Date Mon, 14 Mar 2005 22:36:42 GMT
btw,

the patch:

http://svn.apache.org/viewcvs.cgi/httpd/httpd/trunk/server/core_filters.c?rev=154200&view=diff&r1=154200&r2=154199&p1=httpd/httpd/trunk/server/core_filters.c&p2=/httpd/httpd/trunk/server/core_filters.c

was already in my copy of beta 2-1.3 apache .. so that wasn't it.

the incredibly rapid memory usage increase under sustained load is
something else. My guess, something to do with many timed out
connections per second, that does not show up under normal load. I would
imagine this particular DDOS designer knows of this issue which is one
of the reasons the attack was like that.
