I have been digging down into the code, and adding extra debug output.
In my network read function kodakaio_net_read it seems that poll(...) is
indicating that there is data to read, but sanei_ tcp_read(..) then
returns zero bytes.
If there was no data I'd expect poll to timeout, and if there was some
data, sanei_ tcp_read should return it?
But this is the only network read code I have ever written in c so I am
not too confident it is correct.

This was using xsane.
If I close xsane and reopen it I can scan again.

Are you using a long-running front-end like xsane, or multiple

I can scan any number of times with gaps of less than 30 sec between
scans
without getting this error.
Has anyone ever had a similar experience with any other backend?
Does anyone have an idea what might be the cause?
