SAPCMS is normally used to cache documents in the frontend.

Caching has been deactivated for the duration of this session.

How to fix this error?

This error may have occurred after a long wait time. In the user
parameter SAPCMS_CHECK_TO you can define a timeout in seconds, which
specifies the maximum time the system waits while checking the
destination SAPCMS. When this parameter is set, the destination
SAPCMS is checked asynchronously in a separate session. If a new
session cannot be opened, the check is made synchronously. A
successful synchronous check is much quicker than an asynchronous check,
which is why the
parameter should only be used if this problem occurs frequently.
