Exception on MSG_Disconnect.

[vijay_b4]

Hi, I received an alert saying error text as:

"Exception received: com.jcraft.jsch.JSchException: SSH_MSG_DISCONNECT: 12 Too many connections ",

Any idea what causes this?

Thank you!

Hi Vijay,

Are you using user/pass authentication with SFTP or HTTPS scenarios?,  i think the user can be blocked by several incorrect attempts.

Thanks for the response.

Yes its SFTP sender channel and am using User and Pwd to connect to it.

If this is just incorrect attempts, then I think this can be ignored right?

Hi Vijay,

If the problem is finally the incorrect attempt, you should contact with the SFTP server administrators and to talk with them because they may have to unlock the user or to provide you a right password.

Hi Vijay,

The disconnect code 12 means too many connections, check this link SSH: ssh2 Return Values

what is the resolution, there is no failure recorded neither in message or cc monitoring, Contact SFTP admin and ask to increase the connections?

It looks channel is polling often.. you can increase the SFTP polling under scheduler and specify interval

Hi Vijay,

I think SFTP server only accepting 12 concurrent connections, currently PI opened more than 12 connections to SFTP server and you are getting above error.

Speak to SFTP admin to find out how many connections they accept concurrently.
