FTP message not sent/received due to connection timeout after firewall interrupt

mihir842in Dec 3, 2014 1:33 AM

The FTP connection gets timed out, when there is firewall interrupt. But this FTP connection doesn’t recover even after solving the firewall issue. Due to this, the FTP messages are not sent/received, even after it retries.

Can anyone please help on this issue?

Following are the steps to reproduce it:

Place FTP messages on FTP server
Observe the messages are received
Simulate FTP connection time out by the command : iptables –A OUTPUT –d ip.of.FTP.server –j DROP
Place FTP messages on FTP server
Observe the messages are not received
Solve the firewall issue by disabling it : service iptables stop
Issue: the message is still not received. It keeps throwing connection timed out exception as below:
The same issue also happens while FTP messages being sent.

The global configuration at esb.deployer/jbossesb-properties.xml has timeout as 0(=infinite) and its not overridden in ESB service.

The code doesn't allow the setting of an infinite connect timeout, it currently requires it to be greater than 0 so you will be seeing the default timeout. The code also connects afresh every time it is scheduled which would suggest that there may still be an issue at the network level, assuming that you are still seeing the same 'Connection time out' exception as this is raised by the native VM methods.
