borked apache

[Marcin Król]

Our apache is somehow borked. I can't locate the exact problem, just 
symptoms. I've reported on devel-pl that when browsing any site on 
server (after apache upgrade to 2.0.53-1) lets say, over 50% of page 
views are just rendered blank and clicking on links very often results 
in nothing. No entries in logs are generated when problem occurs. This 
error was confirmed by few other users on devel-pl. 2.0.53-4 seems to be 
affected too. Changing EnableSendfile to off in httpd.conf seems work 
(btw, kernel was not changed in the meantime). The last working version 
I know was 2.0.52-9 which I was using before upgrade.

Now the second problem: I was just trying to upgrade apache from 
2.0.53-1 to 2.0.53-4, and update process _always_ hangs when doing 
second restart of httpd (I'm using prefork). On stopping httpd it just 
says BUSY and doesn't continue after waiting 20 minutes. Looks like it 
doesn't liked those changes: 
http://cvs.pld-linux.org/cgi-bin/cvsweb/SOURCES/apache.init?r1=1.34&r2=1.35
but on the other hand, when using "/etc/rc.d/init.d/httpd restart" 
manually it never hangs...
