... in addition to the above messages, the log is now also
flooded by:
2006-12-05 04:16:29 [5196] LOG: could not rename temporary statistics
file
"global/pgstat.tmp" to "global/pgstat.stat": A blocking operation was
interrupted by a call to WSACancelBlockingCall.
Hm ... there simply isn't anything that holds pgstat.stat open for long,
so this behavior seems independent of any other issues we might have.
Can you find any evidence about what's wrong here?
hope this helps:

those are the file actions that are happening at the same time as the error
log message appears.

the next file actions with pgstat take place some seconds later.
more or less the same thing is happening every 2-3 seconds when the log
errors appear. there was a short pause of ~30min when this error didn't
appear, but for over 40min now it is logged every few seconds. the rc1
doesn't show this behaviour, i've just doublechecked.
