    broken pipe error

    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:

    --[color=blue]
    > [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"[/color]
    --
    /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:
    --[color=blue]
    > FastCgiSuexec on[/color]
    [color=blue]
    > And in a virtualhost directive:
    > FastCgiConfig -multiThreshold 50 -maxProcesses 50 -minProcesses 5
    > -maxClassProcess es 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[/color]
    --

    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.

          Re: broken pipe error

          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
