How does the crash come about? Reading a truncated JSON object back from
the DB, for example?

Title:
You can crash keystone or make the DB very slow by assigning many
roles
Status in Keystone:
Triaged
Bug description:
This is applicable for UUID and PKI tokens.
Token table has extra column where we store role information. It is a
blob with 64K limit. Basically we can do the following to fill the
BLOB
Say user is U, and Project is P
for i =1 to 1000 ( or any large number)
role x = create role i with some large name
assign role x for user U and Project P
create a project scoped token for user U
