Subject Re: Long delay in listDomains API response
Date Sun, 06 Nov 2016 06:01:10 GMT
Dear all,

After researching further, I found out that our problem is exactly the one
reported on this JIRA bug:

https://issues.apache.org/jira/browse/CLOUDSTACK-9405

I am cc-ing dsclose and Wei Zhou on this email. Anyone know if there's any
resolution to the above problem/bug?

On the bug report, Wei Zhou mentioned that he added domain level resource
limitation, may I know if this limitation is configurable? I can't find it
on the Global Settings.

Looking forward to your reply, thank you.

Cheers.
