Please show output of commands: grep memory /var/run/dmesg.boot top -ores -d1 sysctl kern.ipc.nmbclusters It would be also very useful to obtain output of "vmstat -z" in a moment of breakage. _______________________________________________ freebsd-stable@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
