Weird I/O hangs (9.1R, arcsas, interrupt spikes on uhci0)
Hi,
very periodically, we see I/O hangs for about 10 seconds, roughly once per minute.
Each time this happens, the I/O rate simply drops to zero, and all disk access hangs; this is also very noticeable on the shell, for NFS clients etc. Everything else (networking, kernel, ?) seems to continue normally.
Environment: FreeBSD 9.1R GENERIC on amd64, using ZFS, on a ARC1320 PCIe with 24x Seagate
