           Summary: Apache stops receiving new connetions
           Product: Apache httpd-2
           Version: 2.0.54
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: critical
          Priority: P2
         Component: All
        AssignedTo: bugs@httpd.apache.org
        ReportedBy: d@rsn.bth.se


When Apache was sent the following lines using telnet:

GET / HTTP/1.1
Host: whatever.hostname.com
Expect: %8p


It "hangs" for some period of time, and if this is automated in a script the
server stops accepting new connections for the period of time it takes to
"process" the requests.

As of now I have tested it with version 2.0.54-r31 of Gentoo with the hardened
USE flag turned on and on OpenBSD 3.8 (don't remember the version here though).

------- Additional Comments From slive@apache.org  2006-01-12 16:00 -------
Not a security bug because the request does timeout.  But not a proper response
to the request either.  httpd should give an immediate error rather than waiting.

------- Additional Comments From rpluem@apache.org  2006-01-04 21:44 -------
This is because httpd is waiting for more header data. Please lower the value of
TimeOut (default 300 seconds) to mitigate this problem. In general this can
happen with lots of other incompletely sent header situations.
