[keycloak-user] Create user with admin client - throws socket exception..

[Mustafa Kuru]

Hi,

We are using admin client to create an keycloak user.
Socket exception occures sometimes on a test stage. Unfortunatelly i can
not reproduce it locally. The stage is clustered.

>From the keycloak logs i can not find much information about this problem.

This produces blocking sessions in keycloak database. We have to kill them
every time. Otherwise hanging every following call about 5 min. and then
throws exception.
It is very annoying.

Until we upgrade from the version 1.8.1 to 2.x.x we have to find a
temporary solution.
I need to know why the "create user" call causes blocking sessions in
database.

Exceptions looks like:

javax.ws.rs.ProcessingException: Unable to invoke request

...

Caused by: java.net.SocketException: Connection reset

thanks in advance.

Kind regards.
