This is during a sequential write, only one writer. File received via network.
Everything's humming along fine at 11-12MB/s until row 249, there it drops to 2-4MB/s and the machine freezes for 1-2 seconds every 3-10 seconds. Data taken from /proc/diskstats and is in the same order as those fields (documented in Documentation/iostats.txt).
Don't know if it's related to your problems in any way.
