Hi All,
We are having two open fire instances running on clustered. Recently we had observed all user disconnection at particular time in a day. this occurring for 2 to 3days once randomly. Checked openfire logs, logs are overwritten so could not found anything.
When checked cache summary, seeing some warnings. attached the same. Can anyone please suggest what is the ideal values to configure for ones which is in red color.

Thanks
