Hi Folks,
We are facing an issue intermittently in OBIEE 12C. When we hit the URL sometimes it stuck at "signing" page and after some time it gives OBIEE login page as below

Sametime in presentation server logs it throws below error,
[2017-05-17T04:11:59Z] [OBIPS] [ERROR:1] [] [saw.securitysubsystem.checkauthentication.runimpl] [ecid: f3368185-7b51-4d64-9201-37afbcc5971c-00003799,0:3:1] [tid: 1194919680] [SI-Name: ] [IDD-Name: ] [IDD-GUID: ] [userId: ] Odbc driver returned an error (SQLDriverConnectW).
