That's not the case for FreeBSD. I wasn't clear, but statistics I used shows me both used and freed, but kept around elements. And what I posted what the number of really used elements. I don't think it is a leak, because when I unload the module, the memory if freed by ZFS, it's just that backpressure mechanism doesn't work too well. My function is called when there is no memory in the system, is there anything I can do from there to decrease the number of active dnodes? -- Pawel Jakub Dawidek http://www.wheel.pl pjd at FreeBSD.org http://www.FreeBSD.org FreeBSD committer Am I Evil?
