Ok, I started copying messages from my old Zimbra to the new 64bit one.
I started with imapsync but that did strange things when reading the email from a Thunderbird client. In Thunderbird, I select one message but the contents of another message is shown in the preview pane. This has nothing to do with the 64bit build though because I have had this before on a 32bit ubuntu builds. In the Zimbra webclient all looks ok though. On the 32bit build, I then migrated my messages using Thunderbird and that went well so I thought I would try that on my 64bit build as well.

So I started copying through Thunderbird. It started off well but after copying 1599 messages it fails telling me it cannot APPEND.
/opt/zimbra/mailbox.log tells me:

com.zimbra.common.service.ServiceException: system failure: java.io.FileNotFoundException: /opt/zimbra/store/incoming/1206788352246-559.msg (Too many open files)

Here's the log:

Now that I think of it, I also got these messages when migrating through imapsync.

I searched the forums for the too many files open error and hit http://www.zimbra.com/forums/adminis...les-error.html.
I checked ulimit -n and it returned 1024.

I checked /etc/security/limits.conf and it already had the following lines in below the "# End of file":

zimbra soft nofile 524288
zimbra hard nofile 524288

Note that these are different from what the post above says.
As the post suggested I added the following to /etc/pam.d/common-session:

session required pam_limits.so

I logged in with user zimbra and ulimit -n now gave me 524288.
So I restarted Zimbra and now I can migrate my mail to the 64-bit Zimbra.
So far so good!

regards Bart.

Also note how you become the zimbra user whenever you manually start it: [SOLVED] Too many open files error after increasing zimbra_session_limit_imap

I tested my ulimit with su - zimbra.
That returned 1024 before adding "session required pam_limits.so" to /etc/pam.d/common-session and 524288 after adding it.

Just to let you know, I'm still running fine with 5.0.4 beta on Dapper in a 3.1 Xen DomU on a Gutsy Dom0.

I upgraded to 5.0.5 beta yesterday, no problems, still running fine.

I'm now testing a different installation of 5.0.5 beta on a Dapper DomU in a Xen 3.2 Dom0 on Hardy.
