The system is a Twin. In the first post I mentioned this but I probably wasn't clear. The twin unit is this one: https://www.supermicro.com/products/system/2u/2028/sys-2028tp-decr.cfm I've used all components from twin node A and B (cpu / memory / mainboard / controller). I still get the errors. The backplane was the original thought of concern, and that has been RMA'd and replaced - errors continue. I've even swapped out power supplies with another identical unit I have here. In every case the errors continue, until I do this: #camcontrol daX -N 1 (for each drive in the zpool) Then the errors stop. The system errors every few minutes while my application is running. Set tags to -N 1, and everything goes quiet. 16 cores at 100% cpu and drives 80% busy @ ~15k IO p/s, for about 5 hours solid before it finishes a batch, no errors are reported with -N set to 1. If I set tags with -N 255 for each device, errors start again within 5 minutes, and continue every 2-5 minutes, until the batch is finished. -Kyle > I would try, if possible, to swap the controller. > > > > > > > Borja. > >
