Hello,
In a project I use the library oidcrp ver 0.6.3.
During the tests an exception is raised in case of concurrent sessions.

This is the test case:

rph.begin (1st user), state1 is saved
rph.begin (2nd user), state2 is saved
rph.get_session_information(state1) -> Key error is raised

The KeyError exception is raised because the state is not found in state db (state value is correct and state_db implemented as InMemoryStateDataBase).

Do you have any hint to share?

Thanks in advance

Regards,
Davide
