Well I've been running this for a couple of hours:
#!/bin/sh
while true
do
fsstress -p 10 -n1000000 -d . &
fsx-linux -c 1234 testfile &
sleep 180
killall fsx-linux fsstress
sleep 1
done
Chance of close/open is 1 in 1234

testcalls = 95103

So I'm going to have to ask you to investigate further. Does it happen on
other machines? Other filesystems? Older kernels? That sort of thing.
Thanks.
