>FreeBSD 9.1-PRERELEASE #0: Wed Jul 25 01:40:56 EEST 2012 I have the server: 8 cores AMD, 16GB RAM, 4x3TB HDD in RAID10 for ZFS. Sometime wheels fall off the server and the network. Can this clean-up memory for ZFS cache? I enclose a picture with the monitoring system at the time lags. http://imageshack.us/a/img341/9643/memoryusage.png http://imageshack.us/a/img22/6935/nginxclientstat.png http://imageshack.us/a/img19/8817/realmemory.png #cat /etc/sysctl.conf kern.ipc.somaxconn=65535 kern.ipc.maxsockets=204800 net.inet.ip.portrange.first=1024 net.inet.ip.portrange.last=65535 kern.ipc.shmmax=67108864 kern.ipc.shmall=67108864 net.inet.tcp.rfc3465=0 net.graph.maxdgram=8388608 net.graph.recvspace=8388608 net.route.netisr_maxqlen=4096 kern.ipc.nmbclusters=400000 kern.ipc.maxsockbuf=83886080 net.inet.tcp.recvbuf_inc=524288 net.inet.tcp.recvbuf_max=16777216 net.inet.tcp.sendbuf_inc=524288 net.inet.tcp.sendbuf_max=16777216 net.inet.tcp.sendspace=65536 net.inet.tcp.keepidle=300000 net.inet.tcp.keepintvl=60000 net.inet.ip.fw.dyn_max=65535 net.inet.ip.fw.dyn_buckets=65536 net.inet.ip.fw.dyn_ack_lifetime=120 net.inet.ip.fw.dyn_syn_lifetime=10 net.inet.tcp.nolocaltimewait=1 security.bsd.hardlink_check_uid=1 security.bsd.hardlink_check_gid=1 security.bsd.see_other_uids=0 security.bsd.see_other_gids=0 -- Vladislav V.
