Re: Massive CPU use - Command Java

Hi,

Re: Internal server error

Hi,

Do you get any errors when restarting the Zimbra server? Try "zmcontrol status" as zimbra user and observe any issues. Also look at zimbra.log

Thanks,

Yasantha

Re: Docker Zimbra not starting

Hi,

I also get the same error. How can we provide "Yes" to "software license agreement?" when running docker.
