I am facing a problem while saving the configuration on Cisco 3750E. When i try to save below error appears
wr
NVRAM: Unable to read configuration. Try again later.
The switches are in stack. So i checked the configuration lock message as well, It says that the deivce is free to configure but still i could'nt able to save it. The ouput s as below
sh configuration lock

Vijay,
This is expected behavior. When we exit config-mode we need to send the configuration to all switches in the stack, so that every switch will have config on any switchovers. As the config size increases it might take slightly more time.
Try to do it again it should work for you. Else use the secure crt you will not face this issue.

Inayath,
Thanks for the reply.
Tried many times but still the same,i am using secure crt only.
Can i know what is that Owner PID : -1 means?

Whats the firmware running on the devices?
And also have you disable the http server?

I found the cause and the reason, Totally 8 switches are stacked and when i give write command without modifying the config it works fine. But when i modify it wont work for few seconds, later it does. Can i know the reason with the cisco document

}
We have recorded internal bug for the same.

Thanks for the answer.
It could be helpful, if u share a cisco document which says the below

config on any switchovers.
