Running Reaim-7 on a 4G ram disk with 4 processors on Itanium... Every few runs, as the multiprocessing level increases, we see 22 processes hung in sync(), all except one waiting in sync_filesystems() and that one waiting in pagebuf_iowait().
There's lots of free memory, the ram-disk is not full, ... Load average is low; nothing in the logs or on the console.
