--18:26:53--  http://localhost/index.html
           => `index.html'
Resolving localhost... 127.0.0.1
Connecting to localhost[127.0.0.1]:80... connected.
HTTP request sent, awaiting response... 
18:26:53 ERROR -1: No data received.

In the same time, the apache error log shows this:

Comment 1 Martin Wegner 2005-05-12 10:06:05 UTC

Also tried 2.0.53 (downgrade to formerly working version), 2.0.54-r3 and rebuilding all mod_* (mod_php and mod_python here). Nothing helped. Will try more.

Comment 2 Nathan W. Labadie 2005-05-12 13:03:53 UTC

Same problem here. Downgrading to apr-0.9.6 and apr-util-0.9.6 and recompiling apache seems to fix the problem. Must be a bug in apr.

Comment 4 Harm Geerts 2005-05-22 18:52:45 UTC

emerge apr apr-util apache mod_<all_mods_installed>

NOTE: you need to stop and then start apache
restarting (with SIGHUP) causes the childs to segfault

This fixed the segfaulting for me.

You might not need to rebuild the mod_* packages but I'm not gonna waste more
cpu cycles on that :)
