Hi Stian,

Thank you very much for looking in to the issue. We tried with around 6 role creations per second, and I tried switching off realm cache and it had negative impact on the performance of other API s.

Really appreciate if you could suggest us a rough timeline for a fix date. 

Regards,
Malmi

Either don't create roles concurrently or disable cache.

How frequently are you creating roles? Just wondering because if you do it will significantly impact the benefits of the cache as we invalidate a large amount of the cache when roles are added/removed.

The problem you are seeing is most likely down to a race condition when the realm role list (or client role lists) are re-loaded after they are invalidated. I haven't had much time to look at it yet, so I don't know the exact cause or a solution.

Hi Stian,

We have this in production is there any intermediary fix that we can do or any workaround?

Hi Stian/Bill,

I just wanted to highlight that this issue only occurred when realm cache enabled option is ON.

Hi Stian

I have multiple threads creating different roles. Basically one thread will execute all three apis one after another.

When you say method1 is executed in multiple threads, do you mean one thread creates the role and another retrieves it? Or do you have multiple threads creating different roles?

Hi Bill,

Please find the work flow that we have implemented
create user : POST : admin/realms/{realm}/users

Method1 wrapps the following API calls
Create Realm role : POST : admin/realms/{realm}/roles
Retrieve Role : GET : admin/realms/{realm}/roles/{roleName}
Assign Role : POST : admin/realms/leapset/users/{0}/role-mappings/realm

Same for the client roles as well.

Method1 is executed in multiple threads and assign reams role API starts failing with 404 (keycloak log states role not found)

Malmi

Can you give me what REST invocations you are doing? How do you find the role?  How do you create the role? etc...

Hi Bill,

We tried the above fix on top of 1.7.0 by applying the changes from the commits attached to the https://issues.jboss.org/browse/KEYCLOAK-2327 and deployed, and it seems to have the same issue. If you have any further update on this please let us know.

Regards,
Malmi

It's already fixed in master, so if you can try it out that would be great. We should also have a 1.8.1.Final release this week with the fix in as well.

Which version of keycloak?  RDBMS or Mongo?

Hi Everyone,

In my application we create retrieve and assign role subsequently and it seems that even for a small load (2-3 threads) with realm cache enabled option, assign realm role call fails due to role not exist error and 404 is returned from keycloak.

With the realm cache disabled option the load works fine.

Please get back to me if you have any information on any other option we can follow to get this issue sorted or on what action the realm cache will be persisted to DB.

Regards,
Malmi
