Hello all.
9.2-STABLE FreeBSD 9.2-STABLE #0 r261226
highload servers
/etc/sysctl.conf:
security.bsd.see_other_uids=0
security.bsd.unprivileged_proc_debug=0
kern.ipc.somaxconn=4096
net.inet.ip.fw.dyn_max=65536
net.inet.ip.fw.dyn_syn_lifetime=10
net.inet.ip.fw.dyn_ack_lifetime=60
net.inet.ip.fw.dyn_buckets=512
kern.ipc.shmall=6291456
kern.ipc.shmmax=134217728
/boot/loader.conf:
kern.ipc.shmseg="512"
kern.ipc.shmmni="1024"
After 20-35 or more days of uptime,
server stops showing realtime LA: show normal top, but first line not change:
last pid: 29849; load averages: 2.36, 2.32, 2.28
^ ^ ^
| | |
Then, servers stops video output and TCP process in state TIME_WAIT starts grow
until limits:
# netstat -an |grep -c TIME_WAIT
27800
At the console, when I try typing - nothing changes,
BUT when I take out console - I see what I type previously at the monitor.
Is any idea what is that?
