Verifying length of test file
error: expected 15 , got 10
FAIL: small-integration-test.sh

The error is inconsistent in that sometimes I will have 10 lines like above, 
sometimes one more or one less.

Dropping back to version 1.71 tests without issue.

Hi,

I updated new revision as r471 for this issue.

I think that the cause of this bug is fuse's calling function sequence.
Fuse does not wait finishing "release file descriptor" function called by fuse, 
and fuse runs(calls) next processing(commands).
Then s3fs could not clear stats cache information for that file before calling 
next processing, and s3fs uses old stats cache information.

But if use_cache option is specified, s3fs run no problem.
Because s3fs has file cache, and s3fs use(read/write) from this cache file.

So that, I changed codes that s3fs clears stats cache in release function at 
first.

Please check new revision(r471), and if you find other bugs please post new 
issue.
I closed this issue.

Thanks in advance for your assistance.
