Description Petr Muller 2019-07-25 15:19:34 UTC

Description of problem:

Saw many tests to fail, investigated further and found out the node is tainted with a "PLEG is not healthy: pleg was last seen active 19m28.423484988s ago; threshold is 3m0s." condition

Additional info:

Not sure if this is related to the existing https://bugzilla.redhat.com/show_bug.cgi?id=1636053 and/or https://bugzilla.redhat.com/show_bug.cgi?id=1613808, both are reported for 3.x, while this is 4.2 development.
