Original GitHub issue: https://github.com/s3fs-fuse/s3fs-fuse/issues/1031

Version of s3fs being used (s3fs --version)

V 1.82

Version of fuse being used (pkg-config --modversion fuse, rpm -qi fuse, dpkg -s fuse)

2.9.7

Kernel information (uname -r)

4.15.0-48-generic

GNU/Linux Distribution, if applicable (cat /etc/os-release)

Ubuntu 18.04.2 LTS

s3fs command line used, if applicable

s3fs -o allow_other,use_cache=/tmp bucket mountpoint

Details about issue

Continuous increase of cpu and mem usage.

After 10 minutes:
PID PPID CMD %MEM %CPU
25006 1 s3fs -o allow_other,use_cac 4.9 6.7

After 20 minutes:
PID PPID CMD %MEM %CPU
25006 1 s3fs -o allow_other,use_cac 7.6 12.8

etc etc, cpu and mem usage continue to increase until the crash...

The problem started after the upgrade to current LTS ubuntu release.

Temporarily I'm fixing with a cron script that unmount and remount every N minutes...

(P.S. already added bucket mountpoint to PRUNEPATHS in /etc/updatedb.conf)

Could you test with the latest version 1.85? It includes many fixes and 1.82 is several years old.

On my repo 1.82 is the latest.
Is there an alternative repo or I have to install it manually?

I reported https://bugs.launchpad.net/ubuntu/+source/s3fs-fuse/+bug/1828849 to Ubuntu to upgrade their s3fs version but you should try compiling from source in the interim.
