v7.193 ftp proxy traffic with big files

[bitonw]

i get this in the ftp proxy log file

and see this in the kernel log file:

the connection will be dropped...

i tried this with and without ips, no difference. cpu is full 100%. box keeps passing traffic like internet radio and web traffic. web proxy is active as ftp proxy.

Looks like the server has a five-minute timeout on inactive control connections. Do you have a max scanning size limit set?

[bitonw]

yes i have. that's on 50mb. the file i used to test is about 1.4gb

the eth0 -> lan
