High CPU waits

[TeeOrion]

Hi all,

Monit keeps flagging high resource and Portal GUI goes unresponsive and fails to loads widgets. I been tried to search on forum for more information and so far couldn't find anything. Happy to be corrected.



Here is what I noticed and actions so far:

• Fresh install
• /var/log RAM disk is enabled

Log errors:

See this, #23. Also: Did you install on ZFS instead of UFS? If not, your installation may be botched already. Save the configuration, reinstall and restore it.

Thank you for that,

It seems taking Step 23 has resolved the issue
