Error of “NT Kernel Logger: Cannot create a file when that file already exists. (0xb7).”
Today I saw some high kernel mode CPU usage and decided to take a quick look at it using xperf:
xperf -on diageasy
And it dumped an error message immediately:
xperf: error: NT Kernel Logger: Cannot create a file when that file already exists. (0xb7).
And a quick Google search brought me to this page, which turns out the error message was caused by Process Explorer which utilizes ETW to collect network I/O statistics. The error message went away after I closed Process Explorer. Of course this might just be one of the possible causes for the error message, but probably it is the easiest one to get around.
