Memory low. Leave the transaction before taking a break!

What causes this issue?

The memory on your application server is running low.

System Response

You are exclusively using one of the few work processes running on the
application server. So that this does not hinder the other users too
much, the work process is released if you do not work with it for a few
minutes. The system terminates the transaction, causing you to lose data
that you previously entered.

How to fix this error?

Continue to work as normal and exit the transaction before you take a
break.
