I've installed D7 on ubuntu server on my LAN
I've some content types and some of these have file field (attached).
All work fine, but sometimes, when I try to download file (attached), download is starting but it stops in the middle. Bit rate go to 0 kb/s
I've checked all apache and php configuration, I think that all is ok.
I've checked error.log, but there aren't any error
I've run netstat -a and connection is ESTABILISHED but after few time it go to FIN_WAIT1
Can anyone help me please?
