Operation to mounted Goofys S3 does not respond

[yutikayy]

We are experiencing the following issue in our environment and we need your support to identify the cause and provide a solution.

We are using the following commands to connect to S3.

"/root/go/bin/goofys --region ap-northeast-1 --uid=2000 --gid=2000 -o allow_other <AWS S3> /mnt/Goofys/"

For data backup purposes, we regularly upload server files to the mounted S3 area by following commands. Command 2:"rsync -aruv <source Directory> <S3 Directory> >> 2>&1"

Commands 2 is written in a shell script and executed periodically by cron. However, during the operation on S3, the process hangs and we cannot get any response.

While in a hung state, we tried to reference S3 by executing commands such as "ls" on the server, but it also hung and did not output any error messages.

This issue was resolved only after unmounting once with the "umount" command and then remounting to S3 with "goofys".

Since no error message is displayed, we do not know the cause of this issue. We would like to request your support for investigating the cause of this issue and providing a solution.
