Jira startup issue slow

[VenugopalY]

1. Jira startup is very slow. Startup takes more than 20 min? seen lot of java messages. Please find the support.zip for debug purpose.

Below are available Java options (default)

-Dcatalina.base=D: Program Files Atlassian JIRA

-Dcatalina.home=D: Program Files Atlassian JIRA

-Djava.endorsed.dirs=D: Program Files Atlassian JIRA endorsed

-Djava.awt.headless=true -Datlassian.standalone=JIRA -Dmail.mime.decodeparameters=true

-Dorg.apache.jasper.runtime.BodyContentImpl.LIMIT_BUFFER=true

-Djava.io.tmpdir=D: Program Files Atlassian JIRA temp

-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager

-Djava.util.logging.config.file=D: Program Files Atlassian JIRA conf logging.properties

-XX:MaxPermSize=256m

2. Why i see warinig message(WARN anonymous) when AD user login to JIRA system as anonymous?

I am having the same issue. Every time a restart JIRA or stop and start the JIRA service it takes anywhere from 20-30 minutes for it to come up to the login page. I don't see any error MSG's in the logs anywhere.  I tried removing all the Plug-ins and rebooting jir and it came up within a few minutes. Thinking it could be a resource issue i gave it 16GB of memory as well but that did not do it.  

I would like to know if there is a way to speed up the startup of JIRA as it is very time-consuming.

We don't have your support.zip, you're going to have to tell us what the errors are.

Similarly for the LDAP error, there's not enough here to work with - lang.NullPointerException is a very generic error, could be anything!
