Hi,

Looking at MOM logs, the problem seems to be that MOM is configured to use 'vdsmjsonrpcclient' module to communicate with vdsm, but it cannot find this module, probably because it is an older version.

Updating MOM to version 0.5.12 should fix it.

Regards,

Andrej

Network is bonded fail-over.

Sure no problem, mom log attached.

It seems to me that MOM is restarting *very* often:

2018-07-18 06:07:04,909 - mom - INFO - MOM starting
2018-07-18 06:07:20,407 - mom - INFO - MOM starting
2018-07-18 06:07:30,658 - mom - INFO - MOM starting
2018-07-18 06:07:30,658 - mom - INFO - MOM starting

And I totally not expect this. Martin, Andrej, is this the expected behaviour?

Bests,
