Broken Pipe Error

[Frank de Bot]

Hi,

occasionaly I find in my apache logs that fastcgi had a broken pipe
error with php running as fastcgi. the logs are like this:

--

> [Wed Nov 5 18:21:31 2003] [error] [client %ip%] (32)Broken pipe:
> FastCGI: comm with server /opt/guide/ppi.searchy.net/cgi-bin/php.fcgi"
> aborted: write failed
> [Wed Nov 5 18:21:31 2003] [error] [client %ip%] FastCGI: incomplete
> headers (0 bytes) received from server
> "/opt/guide/ppi.searchy.net/cgi-bin/php.fcgi"

--
/opt/guide/ppi.searchy.net/cgi-bin/php.fcgi is the php binary itself.
The error occure randomly and can only me reproduced to visit the site
and "have luck" before an error occures (Once I had my site beat up with
simulteanious wget -m's and all request where perfect, next day I view
the site with my browser "ERROR!" and it suddenly occured :-S

the apache config is like this:
--

> FastCgiSuexec on

> And in a virtualhost directive:
> FastCgiConfig -multiThreshold 50 -maxProcesses 50 -minProcesses 5
> -maxClassProcesses 50 -startDelay 5 -appConnTimeout 0
> -listen-queue-depth 1000
> FastCgiServer /opt/guide/ppi.searchy.net/cgi-bin/php.fcgi -processes 5
> AddHandler php-fastcgi .fphp .php4 .php3 .php
> Action php-fastcgi /cgi-bin/php.fcgi

--

php ignores it as a bug report :-/ When I run php as an external fastcgi
application the broken pipe errors seem to seaze, but webpages are
slowing down.
At the moment I'm running PHP4.3.4RC3 on FreeBSD 4.8

Can anyone tell me, WHY those broken pipe error occure and possible
solutions?

Thanks in advanced,

Frank!

I'm not familiar running PHP as a CGI but... I'm wondering if your scripts
are timeing out. If the problem happens on occassions, it might be during
heavy load, and because of heavy load the script takes longer to run.

There is a function set_time_out() I think that you could try and use and
see if it helps fix the problem.

I've increased set_time_limit to 120, but the broken pipe error remains,
the server wasn't under a big load (5min avg: 0.05). I've once had the
error itself once and it gave a 500 error on the instand I loaded the
page, so I don't think it's caused by timeouts

Hi,

We have been using colfusion MX for quite some time and have been facing
broken pipe error. Following is the exact error message taken out from
coldfusion application logs.

"Error","jrpp-6875","08/10/05","14:34:55","PMG","Operation failed on the data
source named ""eqnew"".Reason of failure ""[Macromedia][Oracle JDBC
Driver]Broken pipe"" The specific sequence of files included or processed is:
/index.cfm "

Last year about the same time we faced this problem and once we updated the
JDBC driver to 3.3, the problem seems to be solved but now it is surfacing
again. When we tried to update the driver ( one which is available for
coldfusion MX 6.1) we got an error while running a query from servlet and hence
we switched back to the old driver. Futher we have checked our server resouces,
firewall logs and network also. Everything seems to be fine.

Appreciate any help to resolve this problem.

Thanking you in Advance.
