Have you tried searching? This has been discussed countless number of times.

can you please give me just a guideline to search

Search for "Waiting for changelog lock".

Thank you very much I solved the problem. But when I add gmail config lines to my xml the service wont start I have to remove the lines in orther to work I got ( he server is temporarily unable to service your request due to maintenance downtime or capacity problems) in my browser.

Probably means you misconfigured something. For example, I see that you're using incorrect quote here:

<entry key='mail.smtp.password’>XXXXXX</entry>
