Re: [users@httpd] (104)Connection reset by peer: core_output_filter: writing data to the network

[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
