Hi,

We are using SFTP adapter to collect the data from Vendor. But we are facing below exception while pooling most of the times. But this issue not occurring for all Channels all are connected to same SFTP.

Hi,

your available sockets are all occupied on the PI system. There are two possible solutions:

1. Change the connect mode from "per file transfer" to "permanently" in the SFTP sender channels, if this is possible.

2. Ask the Basis colleagues to increase max number of open sockets on the OS level.

Kind regards,

Tobi.
