You can renice and kill a process using top. So if you have a running top you can still test this. I've seen this kind of hangs as well, but since updating to current from 15th march it never happened again, but I'm not aware of any commit that might have fixed it, so in the end it just might be luck. I didn't investigate the problem very much, because I have had several Timeout problems with drives that run fine after adding further drives, which turned out to be a insuffcient power supply and everytime I accessed the second pool at the same time I went into troubles with the drives on the first pool. SATA drives seem to be to crappy to tell why they fail :( > ps: -CURRENT from around a month/half months ago still have this problem. Not for me it seems, but as said above, it may be luck. -- B.Walter http://www.bwct.de Modbus/TCP Ethernet I/O Baugruppen, ARM basierte FreeBSD Rechner uvm.
