Checkpoint Failure on Exec Engines

New to Appian Administration. I recently got Appian Administration dropped on me. I have no knowledge on this product and trying best to get familiar with it.
SO.. couple weeks back we had to restart Appian several times do to putting in and then backing out a configuration change.
Ever since then Process Exec 01, 03, and 05 show "ERROR 5 checkpoint failure" doing the checkengine.

Any help would be appreciated.
