Received disconnect: MACs don't match

Post by harryseldon »

I have a transfer that's transferring a good bit of data and then I get the following:

Ý12.440¨ debug3: In write loop, ack for 7677 32768 bytes at 251265024
Received disconnect from <IP address>: 5: MACs don't match

ZosDatasetÝI¨: Closing dataset //<dataset name> before completion


I've turned up verbose logging as high as it will go and don't get any additional information in the error. The transfer is initiating on an internal system and sending to a remote system. We have other transfers to different systems both internal and external to our network that are completing successfully. This process actually completed successfully a week or two ago but has gone back to erroring out again. Any advice for resolving this issue?

This is an issue with ssh, not Co:Z. It is possible that you are encountering this: http://www-01.ibm.com/support/docview.w ... sg1OA51665

If so, you should contact IBM for support.
