fastcgi 'broken pipe' tracebacks

[anthony baxter]

Using FastCGI, I see a lot of these errors in the logs:
2003-07-31T05:50:56 ERROR(200) ZServer uncaptured python exception, closing channel <ZServer.FCGIServer.FCGIChannel connected 192.168.41.2:44683 at 0x2b78b7c> (socket.error:(32, 'Broken pipe') [/opt/local/lib/python2.1/asynchat.py|initiate_send|213] [/app/zope/dev_ekit_code/ZServer/medusa/asyncore.py|send|338])

The following patch makes asyncore catch the EPIPE and close the connection.

so this is my problem to ?
How can I solve this ?
asyncore.diff it's wokring good ?

The problem is that:
I can see in the http error.log:
[Wed Mar 17 16:27:31 2010] [error] [client 62.77.209.29] FastCGI: incomplete headers (0 bytes) received from server "/srv/www/zope/zope.fcgi"
[Wed Mar 17 16:27:31 2010] [error] [client 62.77.209.29] FastCGI: comm with server "/srv/www/zope/zope.fcgi" aborted: idle timeout (100 sec)

And one phyton program cause a drastical slowdown.
16508 zope 15 0 645m 608m 3868 S 99.9 10.2 75:32.29 python
This process busies down one core and the website tell us: "zope internal error" or teh site is very very work slowly after 2-3 minutes later the zope is running contiune.

I don't know why ?

event.log: does it work normaly?
