>          Components: Ranger, usersync
>    Affects Versions: 3.0.0, 2.2.0

> One issue noticed was that during initial sync a deadlock was detected while updating
x_portal_user table which caused the initial sync failure. The subsequent syncs should have
been successful, but because of a missing error case check during update of this user, subsequent
syncs are also failing. 
> From the logs, I noticed that the initial DB deadlock happened for a service user. This
user is being created by usersync during which I also see service creation request which also
creates the service user if doesn't exist.
