CGI app reports broken pipe error

[Stas Oskin]

Hi.

I have a custom CGI application writing binary data to stdout.
Recently, probably after some upgrade, I begin receiving write errors
with the system error Broken pipe.

The only way to proceed writing is to discard the data portion I'm
trying to write and continue.

Can someone advice how to debug this and find the issue? Also, are
there any know recent changes (from this year beginning/last year end)
which could have caused this?

I'm using CentOS 4.4, Apache version 2.0.52.

Thanks,
Stas.

that should mean that the web client disconnected, and your CGI
shouldn't keep pumping out data

prefork MPM and strace -f

Hi.

So the moment the client is gone, and the CGI app attempts to send
data, it will receive broken pipe (as there indeed no pipe anymore)?
Is this the only reason for the error?


prefork MPM and strace -f


Thanks, will try them.
