Hi DeclanOR,

Sorry but currently we don't have any access on the nodes, it was only the customer adminisstrator who explained it to me. According to him, when the CPU Usage reaches 95% of the utlization the Lost Sync error prompts, and VM's on other cluster starts to be frozen. What are other reasons why it happens?

Hi @kmsj13 

It's not really possible to make any assumptions without seeing the systems, at least not in this case. There is a  potential issues which comes to mind however relating to RDA which is necessary for Infosight. This specific issue affects version 3.7.8 only.

This article explains the issue:  https://support.hpe.com/hpesc/public/docDisplay?docLocale=en_US&docId=mmr_sf-EN_US000023409

If you need assistance in terms of the steps on the KB article, please create a support case for us to assist. Basically, if the criteria outlined here is met, and you currently run version 3.7.8, running the command outlined on all OVC's will resolve this specific issue.

If you are not running version 3.7.8, please create a support ticket for additional assistance.

Thanks,

DeclanOR
