Installation of the X4 Server as Service not possible
https://softproject.atlassian.net/browse/X4BUG-852
When installing the All-in-One installation package (see All-in-One Interactive Installation), it is currently not possible to install the X4 Server as a service.
During the installation, make sure that the Install X4 Server as Service checkbox is unchecked before selecting Next.

Increasing or removing the size limit for savepoints
The X4 BPMS uses a WildFly version that throws an error when objects larger than 10 MB are loaded at savepoints, for example, after the manual processing of human tasks within a process.
To prevent this error, you must increase the size limit of the filter or disable the filter. For more information, see Savepoint Configuration for the X4 Server .
