Hi Guys I really need you guys help. Enclose, please find the screenshot. You will find the the server is not able to get information from blade3 and blade10 servers. All other servers are OK. The following approved the connection between the client and server is OK and the client is able to get the host status. It's looks like the client is not able to send the complete report to the server or the server does not know how to process the report. Can anyone help me out? I use TCPdump to listen to the package from client Server side: ------------------------------------------------------------------------- 12:10:50.811256 IP <client.IP>.38443 > 192.168.1.3.bb: S 1654143795:1654143795(0) win 5840 <mss 1412,sackOK,timestamp 1806732208 0,nop,wscale 7> 12:10:50.811281 IP 192.168.1.3.bb > <client.IP>.38443: S 3703070301:3703070301(0) ack 1654143796 win 5792 <mss 1460,sackOK,timestamp 1283960640 1806732208,nop,wscale 7> 12:10:50.850165 IP <client.IP>.38443 > 192.168.1.3.bb: . ack 1 win 46 <nop,nop,timestamp 1806732246 1283960640> 12:10:50.852964 IP <client.IP>.38443 > 192.168.1.3.bb: . 1:1401(1400) ack 1 win 46 <nop,nop,timestamp 1806732246 1283960640> 12:10:50.852978 IP 192.168.1.3.bb > <client.IP>.38443: . ack 1401 win 68 <nop,nop,timestamp 1283960682 1806732246> 12:10:50.853289 IP <client.IP>.38443 > 192.168.1.3.bb: P 1401:1939(538) ack 1 win 46 <nop,nop,timestamp 1806732246 1283960640> 12:10:50.853297 IP 192.168.1.3.bb > <client.IP>.38443: . ack 1939 win 89 <nop,nop,timestamp 1283960682 1806732246> 12:10:50.853327 IP <client.IP>.38443 > 192.168.1.3.bb: F 1939:1939(0) ack 1 win 46 <nop,nop,timestamp 1806732246 1283960640> 12:10:50.853366 IP 192.168.1.3.bb > <client.IP>.38443: F 1:1(0) ack 1940 win 89 <nop,nop,timestamp 1283960682 1806732246> ------------------------------------------------------------------------- Client Side "hobbitclient/client/tmp/msg.<my.host.name>.txt" file16374 ------------------------------------------------------------------------ ... .... ..... postgres 18 0 91856 3112 2704 S 0 0.2 0:00.03 postmaster 16376 postgres 15 0 92000 1180 744 S 0 0.1 0:00.00 postmaster 16377 postgres 18 0 82036 696 284 S 0 0.0 0:00.00 postmaster 16378 postgres 17 0 81164 856 320 S 0 0.0 0:00.00 postmaster 20968 root 18 0 97.7m 1232 944 S 0 0.1 0:00.00 su 20969 root 16 0 65164 1484 1156 S 0 0.1 0:00.01 bash 21028 root 18 0 97.7m 1232 948 S 0 0.1 0:00.00 su 21029 hobbit 15 0 65164 1508 1180 S 0 0.1 0:00.01 bash 21096 hobbit 18 0 3820 480 384 S 0 0.0 0:00.00 hobbitlaunch 21667 hobbit 22 0 62932 1120 940 S 0 0.1 0:00.00 hobbitclient.sh 21671 hobbit 25 0 8652 1000 820 S 0 0.0 0:00.00 hobbitclient-li 21687 hobbit 21 0 12572 944 684 R 0 0.0 0:00.00 top [vmstat] procs -----------memory---------- ---swap-- -----io---- --system-- -----cpu------ r b swpd free buff cache si so bi bo in cs us sy id wa st 0 0 0 1026304 176072 702604 0 0 0 0 5 0 0 0 100 0 0 0 0 0 1026584 176072 702600 0 0 0 2 1008 50 0 0 100 0 0 [clientversion] [clock] epoch: 1208427381.209510 local: 2008-04-17 20:16:21 EST UTC: 2008-04-17 10:16:21 GMT @@ -----------------------------------------------------------------------
