[keycloak-user] LockAcquisitionException and Lock wait timeout exceeded exception in events

Mon Mar 18 17:21:39 EDT 2019

Realm is tenant in my case. I have more than 600 realms and each realm has about 6 clients (excluding what gets shipped by default). There are 2 realm roles and 2 to 3 client roles per client, I have a scriptmapper and 2 groups and about 10 users in each realm.My Max db connection is 30. Let me check that again try increasing it..

  what exactly is "tenant" in your case? Is it client or realm? 
  We know that there are some issues with big number of those entities, so you will probably see issues with 500 or more realms/clients. Maybe it helps to increase count of max DB connections - both at the datasource level in standalone(-ha).xml and in the settings of your MySQL DB. But not really sure...

Hi , 
  I am using keycloak 4.5.0.Final in one on my projects and  i have fairly large number of tenants (> 500). Off late i see frequently  lock acquisation related errors and timeout. 

  I am not able to figure out where and how this is origniating? can you please help? 
  My suspecion is  is this related to events logging? could this be because of farily large number of entrys in the audit/ events table? 
  Note the thread id default task-19354 in the for event REFRESH_TOKEN_ERROR and corresponding thread throwing LockAcquisitionException
