session replication issue
setting of session replication worked well. However, we do have threading
in some products. Like we are hitting the target API and getting response
from there servers. If will not get the response will hit them after some
time and in this case threading not handled by session replication because
of session timeout and shows below errors. After some time the server
starts getting
high load.

How can i address above issue or just by increasing time out value. Please
explain me.

Can you explain this with a little more detail?

The high-load is caused by greater client load, or because of the
replication re-tried, etc.?
