Console log related question

Hi,

I see this error in my console often, assuming it may be some sort of a problem, I want to investigate further.

2015-06-26 5:50:54.134 PM Unknown[1145]: com.apple.message.domain: com.apple.assumes.failure
com.apple.message.signature: D35D0DB2-D7BD-3BE4-8378-062BFE545E1D:62495

com.apple.message.summarize: YES
SenderMachUUID: A31ABDAF-1096-3E0F-8C23-18184DDEAB00

Any idea on what is causing it? Or is it related to libxpc.dylib and what that is? Thank you.

I run Yosemite clean installed with some 3rd party apps on a 2014 rmbp 13". Thanks.
