I find that the FreeBSD ZFSTuningGuide page suggests tuning only for i386. Am I right to assume that I don't need any tuning for amd64, which is my case? Also is it normal that is I get 5.2Gb usage in ARC on a 8Gb system (not really sure)? Btw, after removing all ZFS snapshots today (more than a 1k) the system is still running (not something I can say for the past few days where I've seen multiple reboots a day).. But it's still early to say that the snapshots might be causing this :) Thanks again, Marin > Chris > -- Marin Atanasov Nikolov dnaeon AT gmail DOT com http://www.unix-heaven.org/
