I just noticed these messages in the log of my NetBSD/alpha system
(1.5U, April 27 sources):
Apr 29 01:30:35 yerfable /netbsd: uvn_flush: obj=0xfffffc000a6f6d40, offset=0x7e000.  error 45
Apr 29 01:30:35 yerfable /netbsd: uvn_flush: WARNING: changes to page may be lost!

What's it mean, and is it anything to be concerned about?
