zmmailboxd -com.google.common.io.Closeables warning

Hello Community,

I'm seeing a LOT of warnings in my zmmailboxd.out log, and I'm curious what could be the cause of it:

Code: Select all

May 02, 2016 11:49:17 AM com.google.common.io.Closeables close
WARNING: IOException thrown while closing Closeable.
java.net.SocketException: Socket is closed
        at sun.security.ssl.SSLSocketImpl.checkEOF(SSLSocketImpl.java:1500)

        at com.zimbra.cs.imap.TcpImapHandler$HandlerDelegate$1.run(TcpImapHandler.java:248)
 


Anyone have an idea on what causes this, and should I be concerned?

Thanks!

I have seen this and ignored this for at least a year and a half, it seems the Zimbra
IMAP server uses some Google library that does too much logging.

It does not look like an issue to me. However there is no bugzilla filed on this yet.
