Java 100%

[dmart]

Installing ZCS 6.0.3 64bit on CentOS 5.4 (x64), Quad Core Opteron, 4GB RAM, 4xSATA in RAID 10.

During installation there was constantly a java process taking 100% of one core. The install took upward of 3 hours. I had done at least 4 clean installs of the OS. After a reboot the same thing happens java process at 100%, never starts any Zimbra services. There is nothing in any of the logs it just appears that starting of the services never finishes. I have removed any references to UTF8 in /etc/sysconfig/i18l. Using zmcontrol will spawn another instance of java and does the same thing.

I am at a complete loss here.

Have you disabled the firewall and SElinux? Have you also got a correct hosts file and valid DNS A & MX records? Post the output of the following commands run on the zimbra server:

cat /etc/hosts
cat /etc/resolv.conf
dig yourdomain.com mx
dig yourdomain.com any
host `hostname` <-- use that exact command with the backticks not single quotes

SELinux and iptables/firewall are completely disabled.

Your hosts file should look like this:

127.0.0.1		localhost.localdomain localhost
192.168.0.85		mail.lsbase.com mail

Fix that then shutdown Zimbra and kill any remaining processes then restart Zimbra and see if you still have the same problem. If you still have the problem then post some diagnostics show the offending process.

Did a brand new install on a different server (8x Opteron, 8GB, RAID 10, CentOS 5.4), created a KVM guest with 2 cores/2gb ram with CentOS 5.4. Now it installs more quickly on the VM but every time Java would goto 100% before, it just sits idle. Eventually each task will complete but it takes quite a while (even in the option menu when setting the admin password, it takes about 2 minutes for it to come up, however the server is completely idle.) I can't really provide any diagnostics on anything cause there's nothing happening anymore

After giving this a rest for a week or so I decided to get back at it. Clean install of host, clean install of guest, (Both CentOS 5.4 x64). Same results only this time I noticed if I only allocated 1 VCPU to Zimbra it would start up as expected and work as expected. If I shut that VM down and give it any more VCPUs Java seems to hang when starting Zimbra. If I install Zimbra on bare metal it's fine.
