Connections Rejected due to high load average 98 Time

[jamjam <elliotscan@gmail.com>]

Hello,

 

I am running Nessus 3.0.2 for Fedora Core 4 on a Pentium 4 with 500 MB RAM and a 100Mb ethernet connection.

After scanning ~50 windows servers and workstations I found the following system message:

 

Warning!!!: Connections Rejected due to high load average 98 Time(s)

Load Avg 12: 19 Time(s)

Load Avg 13: 20 Time(s)

Load Avg 14: 18 Time(s)

Load Avg 15: 12 Time(s)

Load Avg 16: 7 Time(s)

Load Avg 17: 3 Time(s)

Load Avg 18: 5 Time(s)

Load Avg 22: 1 Time(s)

Load Avg 24: 1 Time(s)

Load Avg 26: 2 Time(s)

Load Avg 27: 2 Time(s)

Max. Load Avg reached: 27

 

My .nessusrc server prefs are as follows:

begin(SERVER_PREFS)
 max_hosts = 20
 max_checks = 4
 cgi_path = /cgi-bin:/scripts
 port_range = default
 auto_enable_dependencies = yes
 silent_dependencies = yes
 host_expansion = ip
 ping_hosts = no
 reverse_lookup = yes

 optimize_test = no
 safe_checks = no
 use_mac_addr = no
 unscanned_closed = no
 save_knowledge_base = no
 > > kb_restore = no
 kb_dont_replay_scanners = no
 kb_dont_replay_info_gathering = no
 kb_dont_replay_attacks = no
 kb_dont_replay_denials = no
 kb_max_age = 864000
 slice_network_addresses = no
 plugin_upload_suffixes = .nasl, .nasl3, .inc, .inc3, .nbin
 plugin_upload = yes
 plugins_timeout = 320
 non_simult_ports = 139, 445
 checks_read_timeout = 5
 language = english
 log_whole_attack = yes
 throttle_scan = yes
 auto_update_delay = 24
 auto_update = yes
end(SERVER_PREFS)
 

Why were those connections rejected? Is my "max_hosts" set to high compared to the amount of RAM that I am using? Or do I need to decrement the "checks_read_timeout" number?

 

Thanks!
