Can you do a crash test for me?

After few weeks where I have disabled backups and so I do few mb of i/o in a day I confirm that nas hangs again.
So even not using it (but keeping nfs connections always on) crashes the nas.

So this confirm that it is a bug due to long standing nfs connections or something similar. Probably after some time a nfs thread stops working. So with 32 threads, low i/o two weeks are needed before all nfs stops responding.

But I see that:

1) netgear is not interested in bug reports but it is only worried to let me know that it do that warranty on software has expired
2) in the forum I see no one interested in try a bonnie++ on his nas to discover if it is flawed too
3) I have lost many weeks of my time that was precisely the main thing I want to avoid buying a commercial nas.

So now I will throw it in the trashcan and I build a serious nas based on freenas.
