Hello,

since a few days we have a new Intel Server (2xXeon, 32GB RAM, LSI SAS 8708ELP RAID6) with DSS 5.0.DB49000000.3278 running. From a second server (same hardware) we will do some heavy reading/writing (snapshoting/backup) per NFS. Performance is stable at 94MB/s across two switches and buildings for writing a single file per NFS (dd from second server to first server per nfs).
If we do run an backup with many small files (cp -alr && rsync --delete) from nearly complete linux server, the DSS fails. The backup runs in a single thread on the second server. The backup contains then more data than files/MB has been changed. The nfs connection itself doesn't break, but the webinterface crashes and returnes after stopping the backup and waiting a short time. Also i got per mail the following errors:
