FTP connection failure.

[former_member223432]

Hi guys,

We are having a idoc to file interface...it is working fine...but sometime we are getting the below error.in AE and it occurs abruptly

"MP: exception caught with cause com.sap.engine.interfaces.messaging.api.exception.MessagingException: Could not get FTP connection from connection pool (1 connections) within 4,000 milliseconds; increase the number of available connections".

when i resend this error message, it goes succesful..

I just checked wiht FTP connection team, they say the connection is up and running and there is no drop out at their end.

Is there anything else i can check from PI side to overcome this failure?

please advise.

Hi,

Make sure to have Passive Data Connection and the connect mode with Permanently option.

For large files processing , use Maximum Concurrency 1 and set the poolWaitingTime to 0. This will not work for parallel message processing.

Hi Smitth,

In addition to Phani could be a configuration system problem. You should check these notes:

Pay attention to 14 and 21 questions:

Note 821267-  FAQ: XI 3.0 / PI 7.0/ PI 7.1/ PI 7.3 File Adapter 

Check your patch level:

Note 1054456 - XI / PI File Adapter: FTP Connection Errors May Be Ignored

Hello,

Possible reasons for the errors are:

1. The target server is down. Check if the server is available by pinging.

2. FTP services are down. Check if you are able to login using ftp command.

3. Firewall is blocking the connection. Check with the firewall support team.

4. The target server is non responsive. Check with the server administrator.

Regards,

Phani

Hi,

As ur error message is suggesting, increase the concurrency (and add pool waiting time) in file receiver adapter. Chk this article:
