I forgot to mention, the client is just the Firefox browser. Normally
it downloads that files and stores them in the local file system.
What kind of "keepalive" data could be used?

Re: [users@httpd] (104)Connection reset by peer: core_output_filter: writing data to the network
Posted by ch...@eehmke.de.
Hello all,
the problem is solved. It turned out that the cgi application had a bug that
caused error messages to be injected into the downloaded file. I guess this
caused some checksum on length validation check to send a RST ACK package
back. Why this did not happen with other files I must still debug, but when I
removed the code that caused the error message inside the file stream, all
worked fine as it should.
Regards, Chris
