X670-G2 with EXOS 21.1.2.14: Establishing SSH session takes too long

[Chacko]

Establishing a SSH connection with Summit X670-G2, EXOS 21.1.2.14 takes too long.
You have to wait 15-17 seconds, before the prompt is showing.
Generating a new SSH key helps for a short time, but then this problem reoccurs, ~1 week.
We already reinstalled the ssh-module but can't find a solution.

Tried it with PuTTY and SmarTTY, but both SSH-clients are reacting in the same way.
The exsshd-process is in version 6.5.1.69 - cpu and memory are looking good.

Does anyone experienced the same behavior?

As per the CR which was provided earlier by my colleague,Currently what i see the EXOS 21.1.3 is ready to be released either end of Jan or max by mid feb 2017. Already regression test started on this since 5th jan and no more further issue reported yet.
Coming to path release of 21.1.3 (21.1.3p1 is expected around march 2017)

Hello Guys!

We have the same Problem with our X620-16x switches running summitX-22.1.1.5.xos. A "restart process exsshd" does not help. SSH Login lasts 15-30 seconds

Johannes,

A CR# xos0063806 has been opened to address the SSH issue. Our Engineering team has included the fix in EXOS 16.2.2 which is available in our portal. They are working to include the fixes in EXOS 21.1.3.1 & 22.3.1 which is in-progress.

The temporary work-around is to gracefully restart the exsshd process.

I haven't mentioned it before, but the workaround works with X670-G2.
