Hello,

we have upgraded our zimbra systems to 7.1.1.
Now the users experience the following problem:

- they try to move ~200 Mails or more to another Folder (Trashbox, archive folder ...)
- after they do so, the website hangs up and they can't relogin to the webgui.
- imap access also doesn't work anymore
- mails can't be delivered to the mailbox anymore (mailq reports a "Zimbra LMTP server closing connection; service busy")

only a zmmailboxdctl restart helps.

That happens on all our upgraded systems.

Does anyone have any idea to fix that issue?

thanks,
Thomas
