How to repeat:
o Clear all logs
o Generate enough 'Last message repeated' messages for one particular entry (for instance 'Incorrect password from client' to take up one page, but not two.
o Click on any of the page tabs

Suggested fix:
o Fix paginating

Error above is shown in 'infrastructure' log as:

----

And, the same error in the UI log:

Error in the Xwork log (not sure if it's related):

EM-3457's push should address this as well.

A note has been added to the 2.1.1 changelog: 

 The pagination of errors within &merlin_client; for &merlin_server; logging made it difficult to identify the true source of the error.
