This is is probably caused by the Nachi worm. -----Original Message----- From: william villanueva [mailto:[EMAIL PROTECTED] Sent: Saturday, August 23, 2003 10:45 AM To: Plug Subject: [plug] very high load on server
Hello! I have a little problem with a server. Sometimes, the load of the system will sometimes go up as high as 19.xx and everything crawls. I'm running MailScanner and it seems to be the culprit when I suddenly receive a large number of mail. When I run 'top' 10:41am up 114 days, 7:46, 1 user, load average: 8.82, 7.84, 5.76 115 processes: 114 sleeping, 1 running, 0 zombie, 0 stopped CPU states: 0.1% user, 0.4% system, 0.0% nice, 0.2% idle Mem: 262144K av, 109372K used, 152772K free, 47476K shrd, 0K buff Swap: 524288K av, 281624K used, 242664K free 63548K cached The cpu doesn't seem to be the problem so I guess it might be running short on memory. I read somewhere about running 'vmstat' and this is what I got. procs memory swap io system cpu r b w swpd free buff cache si so bi bo in cs us sy id 0 8 0 289208 156260 0 56192 0 0 0 0 0 0 2 1 1 0 7 0 290056 156916 0 56836 0 0 0 0 0 0 1 4 95 0 8 0 290044 155984 0 57640 0 0 0 0 0 0 2 2 96 0 7 0 288856 162148 0 60284 0 0 0 0 0 0 0 3 97 0 12 0 288496 155760 0 66152 0 0 0 0 0 0 1 3 96 0 10 0 287456 155856 0 68200 0 0 0 0 0 0 1 2 97 0 11 0 286804 156028 0 66568 0 0 0 0 0 0 2 3 95 Can someone confirm that the 'b' column indicates I need more memory? Appreciate any suggestions... Thanks! God bless you.
