Keycloak LDAP Sync

[donato.ba...@gmail.com]

Hi together,

We have recently upgraded our Keycloak from version 10.0.2 to version 13.0.1.

We have the problem that as soon as the LDAP sync is running, the keycloak becomes quite slow and does not process the requests anymore, because it pulls the connection pool limit completely.  The limit for the user-federation is set to 20. Maximum Connection Pool limit is set to 100. 

With the old 10.0.2 version it worked great and with the new version 13.0.1 the sync runs slower. Sync runs for about 2 minutes.

This only happens when the LDAP sync is running otherwise the keycloak runs fine.

Has something changed? 

Best regards,
Donato

has anyone an idea? we need some help, there is always a short productive downtime of 2 minutes. We have set the ldap sync every 2 hours now.
