[users@httpd] Broken pipe: write pipe_of_death
Server Version: Apache/2.0.50
OS: Fedora Core 2, 2.6.6-1.435.2.3smp kernel
I've looked all over the place with no extended information about how to
proceed with avoiding this warning in my apache error_log.
[Wed Aug 04 15:29:41 2004] [warn] (32)Broken pipe: write pipe_of_death
[Wed Aug 04 15:29:42 2004] [warn] (32)Broken pipe: write pipe_of_death
I'm receiving these error messages about 20 minutes after I do a reload or
restart of the server and it keeps filling my logs until I hup or restart.
If anyone else has experienced this behavior please let me know as it is
quite annoying. One thing of possible signifigance is this is happening on
2 boxes configured almost exactly the same, load balanced machines. I have
an assumption that it has something to do with this section although it is
a stock setting for apache on fedora core 2.
# prefork MPM
# StartServers: number of server processes to start
# MinSpareServers: minimum number of server processes which are kept spare
# MaxSpareServers: maximum number of server processes which are kept spare
# MaxClients: maximum number of server processes allowed to start
# MaxRequestsPerChild: maximum number of requests a server process serves
<IfModule prefork.c>
StartServers 8
MinSpareServers 5
MaxSpareServers 20
MaxClients 150
MaxRequestsPerChild 1000
</IfModule>
# worker MPM
# StartServers: initial number of server processes to start
# MaxClients: maximum number of simultaneous client connections
# MinSpareThreads: minimum number of worker threads which are kept spare
# MaxSpareThreads: maximum number of worker threads which are kept spare
# ThreadsPerChild: constant number of worker threads in each server process
# MaxRequestsPerChild: maximum number of requests a server process serves
<IfModule worker.c>
StartServers 2
MaxClients 150
MinSpareThreads 25
MaxSpareThreads 75
ThreadsPerChild 25
MaxRequestsPerChild 0
</IfModule>
If anyone has any ideas about how to avoid this warning or to even turn it
off I would greatly appeciate any input. If you need more information then
just let me know and I will provide.
Thanks,
-Jeff

Are you using the Fedora httpd RPM? Can you file a bug on this either
in bugzilla.redhat.com if you are, or in issues.apache.org if you've
compiled from source.
The output of: (as root)
ls -l /proc/`cat /var/run/httpd.pid`/fd/
strace -p `cat /var/run/httpd.pid`
whenever this starts happening would be useful.
