  • We are having an ongoing issue with node 'Receive File Over SFTP' wherein when we attempt to transfer files from 4 different folders simultaneously thru 4 instances simultaneously, we get error for 1 or 2 folders randomly. Is there a limitation in using a common single service account for all folders, as we are currently doing?

  • Reproduce the issue by using 3-4 instances of the same process to load from different folders simultaneously, where each folder has more than 6 files, using the same account for all file transfers. If you are unable to reproduce, we can check about giving sandbox or dev access and/or having a conference call to show how it works on our system. Perhaps you can guide us in formulating a solution to this issue. Thanks in advance!

  • hi ,

    We open a connection for each node execution and the same will be closed at the end of the execution. We have tried to run several transfers parallelly and were not able to recreate the scenario. Please share with us a sandbox environment where we can try to replicate the scenario and analyze the issue.
