Updating a server installation v7 with a very large database (e.g. 4GB db) cannot be completed or, if it completes, leads to a corrupted or unstable database. This occurs because operations executed on db during the update go in timeout e.g. executing database scripts (Redis EVALSHA command) and saving.

A symptom of this problem can be retrieved into server logs, for example:

6948 6948 2023-11-20 13:19:07 421.572 NXSERVER WARNING! NXRedis: Timeout
for command save which is 10 has been reached.
