Odd, why is there two marked as "main"?

From the cachemgr output it looks like the pipe has been opened twice,
and an event got queued on the first which has then been overwritten
before read.
A quick check shows that the pipe initialization is done wrongly. Should
be done in the main thread but is done when first worker thread tries to
notify the main thread, and without any protection leaving it completely
open to races.
