Hello Muzzol!

I suspect this is a bug affecting the Jetty version bundled with Zimbra 7.x, can you please report the information mentioned in section 3.1 of the "How to report a ZeXtras Suite issue" guide? Also, please send your mailbox.log file to community@zextras.com so that I'll be able to have a look...

Have a nice day,

Hello Muzzol!

The Devs confirmed that you stumbled on the "continuation" Jetty issue I mentioned earlier, but luckily enough this is completely harmless and - except for the annoying errors in the logs - has no impact on the proper functioning of the server.

As far as I know, only the version of Jetty shipped with Zimbra 7.2.x is affected, so upgrading or migrating to Zimbra 8.x will get rid of the errors.

Have a nice day,
