Narrowing the problem down, on an error the error handler serialises
the current UI state (which can be very large) to EDN and persists that
in a DB. I am thinking something in there is throwing an exception
which, when I try to log it out, causes the recursion. This throws
another exception and only the top 1024 frames of the secondary
exception is printed.
Thanks all, this is really helpful.
Digging continues.
