Hello janisk,
Our throughput is ~60Mbps at peak (not 640Mbps
)...
And this problem happens in 15 days once... And we don't know what causes it or how does it stop, it just stop...
We have Queue Tree with 45 items...
Mangle 49 (marking http, smtp, ftp and other traffic)...
And 12 firewall rules (mainly blocking spam, and some scanners)...
When all this happens I disable all (mangle, queue, firewall) and nothing changes...
When I remove fibre-optic link (our gateway to world) from RB1000 everything comes fine... But after returning it problem come back and we can just wait...
Any other idea?
