Linux client: warning, got duplicate tcp line
Hi,
One of our Linux RHEL4 client has hobbitclient.log filled with: ... warning, got duplicate tcp line. warning, got duplicate tcp line. warning, got duplicate tcp line. warning, got duplicate tcp line. warning, got duplicate tcp line. warning, got duplicate tcp line. warning, got duplicate tcp line. warning, got duplicate tcp line. warning, got duplicate tcp line. ...
Other systems with same config. and binaries do not complain.
I tried to attach the client data (msg.txt) but this is to big: ezmlm-reject: fatal: Sorry, I don't accept messages larger than 30000 bytes (#5.2.3)
How to debug this?

Odd, I cannot find that error message anywhere in the Hobbit client code.
How to debug this?
Try running the commands in the ~hobbit/client/bin/hobbitclient-linux.sh script by hand; it has to be one of those that generate this error.

$netstat -ant ... ... tcp 0 0 130.223.27.74:993 130.223.131.51:49158 ESTABLISHED warning, got duplicate tcp line. warning, got duplicate tcp line. tcp 0 0 130.223.27.74:993 130.223.131.51:49159 ESTABLISHED
Thanks Henrik :-)
I'll try to find out what this error from netstat means.

Thanks for the info but the host generating these errors has neither sysctl net.ipv4.tcp_tw_reuse nor sysctl net.ipv4.tcp_tw_recycle set.
Redhat seems to be willing to correct this sometimes...(Work is underway at the moment to suppress these messages in further releases of Red Hat Enterprise Linux but is not a high priority because of the messages benign nature)
In the meantime I patched the netstat -ant for this particuliar client (hobbitclient-linux.sh):
echo "[ports]" netstat -ant 2> /dev/null
