Therefore it requires to actually open file for reading that can potentially pollute system memory by open file descriptors (the limited number of which is usually available) and always consumes a large number of resources. I'm currently working on providing imon-like interface for FreeBSD to monitor fs events in efficient way. Currently, timer-based monitoring is the most efficient way, IMHO.=20 --=20 Stanislav Sedov MBSD labs, Inc. <ssedov@mbsd.msk.ru> =F2=CF=D3=D3=C9=D1, =ED=CF=D3=CB=D7=C1 http://mbsd.msk.ru -------------------------------------------------------------------- If the facts don't fit the theory, change the facts. -- A.
