vmware failed to read header on stream tcp n7vmacore15systemexceptione connection reset by peer

As I mentioned we have introduced VMware Log Insight application. I really like this VMware product, but the others too 🙂 Simple and it is working well.


Today I find this error message on our one host:

Hostd: error hostd[66282B70] [Originator@6876 sub=SoapAdapter.HTTPService.HttpConnection] Failed to read header on stream <io_obj p:0x64b7765c, h:42, <TCP ‘’>, <TCP ‘’>>: N7Vmacore15SystemExceptionE(Connection reset by peer)

I started to Google it, and I find this VMware Kb Article:


So this is known issue and no solution yet.

Moving a managed ESXi/ESX host from one vCenter Server to another vCenter Server

In our environment, we have 3 datacenters. The legacy consist of IBM blade servers with virtual vCenter, and the new consist of Cisco UCS blade servers, with other vCenter. This is virtual same. We guessed that insert IBM servers into vCenter of Cisco servers. I found a vmware KB articel. This is very easy procedure, if they aren’t use vDS.
