We should follow the precedent of AWS CLI (and related SDKs) as closely as possible: https://docs.aws.amazon.com/cli/latest/userguide/cli-configure-files.html#cli-configure-files-where As I understand it `get_access_keys` should consider `%UserProfile%` when using Windows. In addition to...

Could you test with master? It includes 3958450c05a272a7e4536a32060ab991d8d636f2 which may close these temporary files properly.

Please reopen if symptoms persist.

Which flags do you pass to s3fs? Valgrind reports a leak when using `-o use_cache`: ``` (2) ==1105142== Open file descriptor 20: /tmp/s3fs-cache/.s3fs-integration-test.mirror/3e6990c7.tmp (2) ==1105142== at 0x51F4544: open (open64.c:48) (2)...

s3fs has a blind spot in its testing, both large files blocked by #1543 and server-side encryption blocked by gaul/s3proxy#402.

I successfully wrote a 5 GB + 1 file with `s3fs -o use_sse -o max_dirty_data=-1` using the test `junk_data` command. Could you give some other instructions to reproduce the symptom?

@michallula could you look into this?

Would re-reading the credentials file periodically be enough to address this issue?

How often does the AWS SDK refresh its credentials? Does `duration_seconds` describe this or is it something else: https://docs.aws.amazon.com/sdkref/latest/guide/setting-global-duration_seconds.html

@nmeyerhans Any chance you could look at this? This appears to be one of the most common AWS issues.
