SFTP server getting blocked because of multiple threads/Messages from PI

[former_member585940]

Hi Experts,

We have two interface where we are placing the file at SFTP server.

Message flow is high(100 msg per hour for each interface).

The issue is, during peak time, the SFTP server gets locked.

While checking with server team, I came to know it was Thread issue.

When PI attempts to logon to the sftp server at the same time across mutiple threads, their server sees it as DOS attack and block the IP.

The SFTP server can be connected to maximum five threads at the same time.

I am not sure how and where do we maintain number of threads in PI.

If you have any ideas about this, please share your knowledge.

I will really appreciate your quick response.

Regards,

Vikram

Hi Vikram - Did you try adjusting the maximum concurrency value?

Maximal Concurrency

This parameter determines the maximum number of messages that are processed in concurrently at any point of time.

Also have a look at the below documentation to restrict the consumer threads-
