SubjectRe: PROBLEM: nfs & "Warning - running *really* short on DMA buffers"
   It doesn't seem rate limited to me, it floods the console and log 
files. If i can't tune the vm settings to decrease the likelyhood of
this error message, what can i do? Is rate limiting the error message
at scsi_merge.c a good idea?


Thanks,
Pedro
