Hello, thank you for answer Peter.
But what do think about this:
--------------------------------------
# netstat -an |wc -l
29616
# netstat -an | grep -c TIME_WAIT
27800
+
kernel stops showing realtime LA: show normal top, but no changes at first line
output:
load averages: 2.36, 2.32, 2.28
^ ^ ^
| | |
--------------------------------------
sysctl net.inet.tcp.msl and tcpdrop do not help,
after killing TIME_WAIT this connection state start grow again till 27800.
I have to reboot servers couse some apache process goes to <defunct> state
and stop responding.
Normal traffic and no ddos at this moment.
Again, this problem (netstat & LA) happen at the same time.....
