Connection Issue

girishb — Wed, 13 Sep 2006 17:21:41 GMT

Hi,

We have two Java Web Server in two different locations: CityA and CityB. The Servers are installed with RHEL.

Issue: The server at CityB can establish connection with server at CityA for couple of hours and then connection gets disconnected.

When we reboot the server at CityB, it again establishes connection for couple of hours before disconnecting.

What could be the cause of the problem and how do I resolve this issue.

Your early response is really appreciated.

Thanks
Girish

What sort of connection is it between the servers? TCP? UDP? ESP? Something else?

Do any of the connection details have any timeout's (other than the underlying protocol timeouts) associated with them? (You may need to wade hip-deep into Java documentation to find them).

What sort of traffic load is going between the hosts?

If you set up a simple 'ping' between the hosts for the duration, do you get any periods of failures?

Connection between two servers is tcp and it connects using the port 8080.

Traffic load is around 600-800 users connect to these servers every day.

I'm not sure about the time outs. I'm new to networking arena and I'm trying to understand the problem.

I need your suggestions what needs to be done.

If you set up a simple 'ping' between the hosts for the duration, do you get any periods of failures? - I will check this out and get back with the result.

Thanks
Girish

Log of your Java Web Servers from both linux servers may help.

Is restart of CityB webserver help?
