From Bugzilla Helper: User-Agent: Mozilla/5.0 Galeon/1.2.7 (X11; Linux i686; U;) Gecko/20030131 Description of problem: I've searched bugzilla but didn't see anything like this. I've got apache 2.0 server running, pushing static HTML pages and one perl CGI program. What happens is that httpd processes apparently get hung in the "Sending Reply" phase. This causes the master httpd process to keep spawning sub-processes until it hits 152 processes (two more than the config file MaxClient limit of 150). It then stops serving any data at all. The system is a dual CPU i686 with 0.5GB memory. /etc/init.d/httpd fullstatus before reaching the 150 limit gives the following scoreboard: Apache Server Status for localhost Server Version: Apache/2.0.40 (Red Hat Linux) Server Built: Apr 7 2003 09:19:34 _________________________________________________________________ Current Time: Friday, 09-May-2003 10:15:12 EDT Restart Time: Thursday, 08-May-2003 22:18:13 EDT Parent Server Generation: 0 Server uptime: 11 hours 56 minutes 59 seconds Total accesses: 75 - Total Traffic: 271 kB CPU Usage: u.28 s.28 cu.03 cs.04 - .00146% CPU load .00174 requests/sec - 6 B/second - 3700 B/request 126 requests currently being processed, 9 idle workers WWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWW WWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWW_W_ _______......................................................... ................................................................

Open slot with no current process After that it lists all the busy processes and what they are sending. In my case, it's all different types of files including jpgs and html files. It's not any one file, it's not the single CGI program, it's basically everything. This site worked fine with Apache 1.3.X. I tried switching to the 'worker' version and although that version doesn't spawn a bunch of processes, it still reports stuck processes like the normal version. Version-Release number of selected component (if applicable): kernel-smp-2.4.20-9, httpd-2.0.40-21.1 How reproducible: Always Steps to Reproduce: 1. See Description. 2. 3. Additional info: I'd call this a high priority bug since my web server is essentially useless at the moment.
Can you attach your httpd.conf and error_log?
In trying to get the error log and conf files together to send to you, I noticed that I didn't have the full path to /usr/sbin/rotatelogs in a log directive, just "|roratelogs logfilename". No error messages were printed on a "/etc/init.d/httpd configtest" but no logs were being generated either. After I fixed that, the problem went away. Sorry for wasting your time but this may come up for someone else.
OK, thanks. httpd-2.0.45 upstream has better reporting of failures to spawn piped log programs.
