Gateway daemon startup fails due to dirty address space

The Gateway daemon fails to start because the address space where it runs has previously been used for running non program-controlled code.


The Gateway daemon fails to start with the following error:

CTG9549E Gateway daemon failed to start, see Gateway error log; the log location is defined by configuration file file name

Probable cause

The CICS® Transaction Gateway zFS (Hierarchical File Store) is mounted with NOSETUID.


Ensure that zFS is mounted with the default of SETUID.
