SMBJ TREE DISCONNECT while iterating thousand of files #427

Open shankaranselvaraj opened 5 years ago

shankaranselvaraj commented 5 years ago

I am trying to read the files from Samba server which is working fine and session is also not closed but getting below error. After restart the server it is working fine with TREE Disconnect issue. Is there anything related to opening of share path multiple time (as it is running in thread for more number of files) like this code session.connectShare(PATH) ?

You need to figure out for which reason the transport got disconnected. That will be in another part of the logging.

This is what i am getting in entire logs. it is not happening all the time it is happening intermittently. Need help on resolving. As of now , restarting application server resolving this issue., but need permanent fix
