Hello > That looks odd, the output of top shows 0 swap usage, but also 0 > resident memory for most of the processes... Yes very odd. After server restart or after restart all deamons processes working normally (in memory not in SWAP) for few (1-3) hours. Then start odd swapping. And this is not temporary (for the possible disappearance of the "swapping trigger") only lasting behavior. Process is moved from SWAP to memory if is not idle. And back to SWAP after idle few seconds. Now after 10 h from write this thread still 84 processes is in swap. procs memory page disks faults cpu r b w avm fre flt re pi po fr sr ad0 ad1 in sy cs us sy id 0 0 84 14863M 682M 315 0 0 0 331 546 0 0 89 1769 722 0 0 100 After restart all processes procs memory page disks faults cpu r b w avm fre flt re pi po fr sr ad0 ad1 in sy cs us sy id 0 0 0 13908M 1213M 318 0 0 0 335 547 0 0 89 1775 722 0 0 100 SWAP partition is gmirrored - it has no significance ;) # Device Mountpoint FStype Options Dump Pass# /dev/mirror/swap none swap sw 0 0 /dev/mirror/root / ufs rw 1 1 /dev/mirror/tmp /tmp ufs rw 2 2 /dev/mirror/var /var ufs rw 2 2 /dev/mirror/usr /usr ufs rw 2 2 /dev/mirror/home /home ufs rw 2 2 tmpfs /var/pgsql/data/pg_stat_tmp tmpfs rw,size=2m,uid=pgsql,gid=pgsql,nosuid 0 0 Similar problem is in thread: http://lists.freebsd.org/pipermail/freebsd-hackers/2014-January/044040.html Best Regards
