Summary: [info]...Invalid argument: core_output_filter: writing
data to the network
Product: Apache httpd-2
Version: 2.0.63
Platform: All
OS/Version: All
Status: NEW
Severity: normal
Priority: P2
Component: Core
AssignedTo: [email protected]
ReportedBy: [EMAIL PROTECTED]
Hello,
today, I was debugging a CGI application, which after logging in, writes
some HTML data to the document root and redirects the client to it.
But the redirection was not successful, the request was answered with a
closed connection. The entire response was missing.
Since this runs on a clustered environment (DocumentRoot is shared over
NFS), I thought this was an NFS problem, because I could receive the
content on the second server. Long story short, I was off the track.
After I set the LogLevel to debug the following message appeared in the
ErrorLog:
[info] [client 160.xx.xx.xx] (22)Invalid argument: core_output_filter:
writing data to the network
I grepped the httpd source for this message to get an idea what's going
on here and found the FAQ entry. EnableSendfile Off, everything is fine
now.
But I really think that this should be at least an error instead of an
info. httpd was not able to send the response, this is worse than "file
not found" which is logged as an error.
Here is the patch:
