Trying to migrate a user from one Zimbra host to another with the following command:
/opt/zimbra/bin/zmmailbox -z -m user@domain.com postRestURL "//?fmt=tgz&resolve=reset" /tmp/user_archive.tgz

Getting the following error:
[] INFO: I/O exception (java.net.SocketException) caught when processing request: Broken pipe
[] INFO: Retrying request
ERROR: zclient.IO_ERROR (Unbuffered entity enclosing request can not be repeated.) (cause: org.apache.commons.httpclient.ProtocolException Unbuffered entity enclosing request can not be repeated.)

Archive size is 395M. Any help is greatly appreciated.

Thanks in advance.
