Hi, Just installed 2009.06 and encounter 100% kernel usage when I copy large files from the network to a zpool. I have tried to use both the smb client and rsync to do the transfer.
The transfer begins with no issues, however, after 20-30 seconds, kernel usage (as indicated by top) jumps to 99%-100% and stays there, even if I terminate the transfer. When the kernel usage is that high, the system will slowly respond to some commands in a shell, but will not allow any logins or su commands to execute. If I leave the system, sometimes it will return to a normal kernel usage, othertimes, I have to reboot the box. There doesn't seem to be any disk activity when the kernel hits 100%. I first suspected a problem with the e1000g network driver, however, the problem still persists if I change it to RealTek Gb card. I have tried to do a dd copy from /dev/null to the zpool, however, that doesn't seem to exhibit the problem; it only seems to happen during a network transfer to the zpool. I'm not sure how to diagnose the issue as I am a beginner Solaris user, hoever, this problem didn't seem to exist under the same hardware running Ubuntu. I'm not quite sure if this is solely a network issue, a zfs issue, or a combination of both. Any help would be greatly appreciated.
