The CIFS session is not disconnected even if the session timeout time is exceeded.

Hi,

The session timeout time is the default setting of 900 seconds, but the CIFS session is not disconnected even if the session timeout time is exceeded.
The status of the session is described below.

The following knowledge states that if the number of shares is one, it will be disconnected, but it was not disconnected.

https://kb.netapp.com/Advice_and_Troubleshooting/Data_Storage_Software/ONTAP_OS/Why_does_vserver_cifs_session_show_show_sessions_with_long-running_idle_time

The version of ONTAP I'm using is ONTAP 8.3 P3.
In this version, isn't it disconnected even if the idle timeout time is exceeded?

Why isn't the session disconnected ?

if you will upgrade to 9.7 p8 or higher ONTAP Should Idle Out CIFS Connections and Sessions with Open Shares but no Open Files in Both Multichannel and Non-multichannel Scenario

Hi, Mjizzini

Thank you for your reply.

As you told me, when I checked the number of File Open, it was opening the file.

Node Vserver Session ID Connection ID Open Shares Open Files Connected Time Idle Time
node-01 fa1 1 661124148 1 1 42d 21h 12m 2s 26m 35s
node-01 fa1 1 808398530 1 1 30m 55s 29m 54s
node-01 fa1 1 808082998 1 1 2h 24m 57s 1m 22s
node-01 fa1 1 808405294 1 1 26m 7s 25m 25s

Thanks to you, I understand why I don't time out idle.

My Best Regards,
