Hi Community, we have a UTM that has 35 red tunnels connected (configuration: all split tunnel) , each red has 10-20 clients to handle, most of them connected simultaneously.
Since a few days the tunnels are randomly dropping packages, they don't even appear in 'conntrack' anymore. However kernel dmesg contains various warnings. The license we use has "unlimited connections".
Kernel dmesg error log:
[13496615.819898] RED: red_tunnel_xmit: tunnel id 12, too much work queued, dropping packet [13496642.261429] RED: red_tunnel_xmit: tunnel id 34, too much work queued, dropping packet [13496680.631771] RED: red_tunnel_xmit: tunnel id 7, too much work queued, dropping packet [13496801.900976] RED: red_tunnel_xmit: tunnel id 17, too much work queued, dropping packet [13496928.608491] RED: red_tunnel_xmit: tunnel id 3, too much work queued, dropping packet
Someone has a clue how we can increase reds work query performance? Please let me know. I found no information on the web about this issue. Any help is appreciated.
