Mountpoint_s3::fuse: release failed

Question

I have mounted an s3 bucket using mountpoint_s3 with the following command:
`mount-s3 --allow-root  --read-only my-bucket-name mymountdir`

It mounted without errors and I can see the files from the S3 bucket in the mounted directory.

But now I am seeing many errors in syslog that look like this:
`mount-s3[1369]: [WARN] ioctl{req=2340 ino=40 fh=133 cmd=21505}: mountpoint_s3::fuse: ioctl failed: operation not supported by Mountpoint
mount-s3[1369]: [WARN] release{req=2346 ino=40 fh=133}: mountpoint_s3::fuse: release failed: unable to unwrap file handle reference`

Why am I getting these errors and what should I do to keep from getting them?

This has been logged as a bug, but was closed due to lack of information from the user that reported it back then https://github.com/awslabs/mountpoint-s3/issues/582

Could you re-open that bug and provide the more detailed information that was requested by the AWS engineer https://github.com/awslabs/mountpoint-s3/issues/582#issuecomment-1784710456

if that's not possible then log a new issue https://github.com/awslabs/mountpoint-s3/issues
