I have a system which exports small files in great amount! one folder have 62000 files and I export 16 of those folders currently. I export them to mounted NFS folder.
If NFS is shared from ext4 - no problem, but shared from sdfs - and I have this error.

max-open-files="1024" set vdedup1tb2-volume-cfg.xml

HI!
I've tried safe-close="true" and safe-close="false"
problem still persists

since service NFS have a max open file 1024 and max-open-files="1024" in xml is set, I've decided to check path that is opened by process during this error

most of those opened files is DDB

you can try it yourself by the way.
I think it is better if you reproduse this problem in your environment.
export schema from SAP HANA database on NFS+sdfs storage

I've checked this one Datish Cloud Storage Gateway, - it has same problem

I found resolution of my problem!!

The source of problem is interaction of SDFS + NFS3 server ontop +NFS4 client.
echo 0 > /proc/sys/fs/leases-enable is workaround.
It does not resolve original problem of NFS, but makes it working.
i think you can close this issue.
