Subject: [keycloak-user] Exception thrown when deleting user through API (when Keycloak
servers are highly available)
Hi,
We're running into a bit of a problem when trying to delete users through the
API. The error returned is of HTML format with 500 error code:
<html><head><title>Error</title></head><body>Internal
Server
Error</body></html>
Please note:
- We're using Infinispan for userSessions, realmCache and userCache. Rest of
the data is in MySQL.
- Issue only occurs when Keycloak servers are highly available (2 servers in
our case). Works fine when only one server is up.
Logs reveal that this is possibly a serialization issue related to
Infinispan:

Our Keycloak HA system works fine except for this issue. Please advise on how
tackle this.
