WSO2 Identity Server - Tenant Admin Login failure - Error occurred while getting tenant user realm for tenant id

Question

I have started facing problem with tenant admin login to the WSO2 Administrative console at random intervals. I am using the WSO2 Identity Server 5.1.0.

    TID: [46] [] [2016-09-04 19:09:10,344] @tenant1.edu [46] [IS]ERROR {org.wso2.carbon.core.util.AnonymousSessionUtil} -  Error occurred while getting tenant user realm for tenant id : 46

During this time I can login to the WSO2 Administrative console using the super admin account. However, all the tenant admin logins are failing. The issue goes away once the identity server is restarted.

Any help in this regard is appreciated.
