How do I fix this error

[Jeffrey Lee]

I was mucking about with the server.xml file in an effort to switch to using Apache as the front end. Along the way I ended up with the following error:

note The full stack trace of the root cause is available in the Apache Tomcat/6.0.35 logs.

I had enabled the mod_proxy for Apache, but have now disabled it.  I also attempted to revert to the server.xml file that was working, but this has not helped.

Here is the contents of that file:

<Server port="8000" shutdown="SHUTDOWN" debug="0">

                />

    </Service>
</Server>

I had also changed the base URL, but I was able to manually change that back in the bandana table, but no improvement.

I'm assuming that there is still something broken in my server.xml, but am at a total loss.

After much work with the Atlassian team (mostly on their part) and Hercules, we determined that the Felix folder in osgi-plugins-cache had taken on the wrong permissions. I suspect that this occurred when I inadvertently ran startup as root, instead of start-confluence as the confluence user. It then created a cache file with the wrong owner. Deleting the folder fixed the problem.

Exact same problem! It happened when I was trying to move connector port to 80. I think current documentation doesn't talk about moving to port 80 from 8090, and issues like it's not recommended to directly use port 80 because of security concerns.

Your comment is unrelated to that specific answer

[Jeff Dickerson]

I encountered this error when migrating from one database server to another. The issue turned out to be that the new database server didn't allow access from the confluence server.

[孙国权]

I have encountered this problem and it same with you the log expression.

Following is my resolution:

Reason: The mysql database access password is not consistent with confluence.cfg.xml

Resolution: Set correct password in confluence.cfg.xml

Hi,

If you have changed nothing else, I'd suspect this to be a problem of database connections, however more information could be found in <CONFLUENCE-HOME>/logs/atlassian-confluence.log

The above is a general error, that could mean corrupted plugin cache, database problems, indexing errors, etc.

Please let me know what you can find in the mentioned logfile. I also encourage you to open a support ticket at http://support.atlassian.com where we can assist you.

Kind regards,

Peter

I'm not entirely sure what I'm looking for but here is an excerpt from that log file that might be of use?
