Probably due to the new dnscache config, pop.isti.cnr.it is resolved to the external IP, not the 146.48.80.25

I'm triyng to workaround with the internal IP in /etc/hosts, let's check if this temporarely solves the problem.

the Gateway email parser still cannot connect to pop.isti.cnr.it, 995 due to ConnectException

As we are not able to contact the responsible for the pop isti server, I'm going to implement a temporary fix on the email parser that is going to allow to change the polling interval at runtime.

patch is ready, going to deploy it around 19 today. (although it won't solve the problem completely)

runs every 5 minutes now, configurable by editing the property (pop3pollinginminutes) on CATALINA_HOME/conf/gcube-data.properties file

Updated by Massimiliano Assante over 8 years ago

In the next release the Email parser allows not only to change the polling interval but also to exit the process by setting a polling interval < 1.

Apart from this it seems that 5 minutes are enough for not receiving ConnectException by pop isti. However I believe that 5 minutes is a long time to react to a post reply or soever. The issue remains, perhaps 2 minutes would be ok.

I'm closing the incident as we have a temporary fix, will create a task to work on the ConnectException issue if polling time is less than 5 minutes.
