I'm really not sure what the problem is, I'm logging with a server in different countries and they send through TCP the logs to a central server. The problem I'm having is that the central server is not dropping TCP connections that no longer exist. As an example: CENTRAL SERVER: TCP Local Address Remote Address Swind Send-Q Rwind Recv-Q State -------------------- -------------------- ----- ------ ----- ------ ------- CENTRAL.shell syslogA.33969 5840 0 10136 0 ESTABLISHED CENTRAL.shell syslogB.4930 5840 0 10136 0 ESTABLISHED CENTRAL.shell syslogC.33924 24820 0 8760 0 ESTABLISHED CENTRAL.shell syslogC.33925 24820 0 8760 0 ESTABLISHED CENTRAL.shell syslogD.44925 5840 0 10136 0 ESTABLISHED CENTRAL.shell syslogE.32783 24820 0 8760 0 ESTABLISHED CENTRAL.shell syslogC.33926 24820 0 8760 0 ESTABLISHED CENTRAL.22 host.1624 51968 0 10136 0 ESTABLISHED CENTRAL.shell syslogD.44934 5840 0 10136 0 ESTABLISHED SYSLOGC: TCP: IPv4 Local Address Remote Address Swind Send-Q Rwind Recv-Q State -------------------- -------------------- ----- ------ ----- ------ ------- syslogC.33926 CENTRAL.shell 8760 0 24820 0 ESTABLISHED SyslogC.22 host.4663 57920 0 24616 0 ESTABLISHED Notice that the active conection is the one from SyslogC port 33926, but CentralSyslog has 3 established connections (33924, 33925 and 33926), 33924 is active since some days ago, but doesn't exist in the original server. The problem is that my total connections allowed start to fill up and then I can no longer connect. Any ideas on what could this be? Thank you.
