Debugging comm with (dynamic) server aborted

This is Apache2 on Dreamhost (shared hosting)

According to their wiki they say the config is:

FastCgiConfig -autoUpdate -initial-env RAILS_ENV=production -idle-timeout 120 -maxClassProcesses 5 -killInterval 300

At times I see errors like this:

[Tue Oct 31 05:26:34 2006] [error]  FastCGI: comm with (dynamic) server "/home/bmoseley/trac" aborted: (first read) idle timeout (120 sec)
[Tue Oct 31 05:26:34 2006] [error]  FastCGI: incomplete headers (0 bytes) received from server "/home/bmoseley/trac"

I have three ways to access this application -- two via Fastcgi:

    index.cgi       - cgi interface
    index.fcgi      - fastcgi
    trac            - in .htaccess SetHandler fastcgi-script

"trac" is a symlink to index.fcgi.

Requests for /trac were working fine last night.  Today, /trac hangs
and reports the errors above, yet requests for /index.fcgi work fine.

What causes that "comm with (dynamic) server" error?


Does not seem related to load as sometimes it works when there's higher
load and right now when I tried load was low.




The index.fcgi script is a wrapper script for running Trac:

    $ cat index.fcgi 
    #!/bin/bash
    TRAC=/home/bmoseley/trac

    export PYTHONPATH=$TRAC/lib/python2.3/site-packages
    export PATH=$TRAC/bin:$PATH
    #export LD_LIBRARY_PATH=$TRAC/lib

    export TRAC_ENV=/home/bmoseley/swishtrac

    exec $TRAC/share/trac/cgi-bin/trac.fcgi
