How thick is the wall? It could simply be too thin for effective shadow rendering
Shadows (or rather the light) will need to push through surfaces a bit to avoid shadowing appearing on the lit side
Resolution and bias settings affect that but there's practical limits of how much you can tweak those
Easier to use thicker walls, or light layers if you need absolute precision
The wall is big, i think i've found the problem with bias in shadow option
It doesn't look big relative to how blurry your shadows are, which suggests that the resolution is low
It may be lower than your specified 1024 as you have many lights, so as the info box says the resolution may be automatically reduced
Bias values can be tweaked only up to a point, because their purpose is to strike a balance between shadows leaking / disconnecting versus light leaking
But i got the problem too on the floor
It's similar, but different
Also affected by resolution and biases, but that particularly is caused by the new "high" quality shadow filtering iirc
It blurs the shadows in a way that totally flat geometry seams will be revealed
Which is not the same as light leaking through a wall
Because with some modifications on the bias, i don't had anymore problem on the floor and also on the wall
