Details about issue

I'm getting random SegFaults while transfering (uploading) files using rsync encrypted by gocryptfs. this usually happens after a couple hours / days and I'm unsure why.

The S3 backend is a S3 compatible Ceph cluster.

Any ideas?

Can you try running s3fs under Valgrind which may reveal the source of these symptoms?

Could you test again with 1.85 which includes f53503438c?
