aix.user.attr.nofiles
This configuration parameter specifies the soft limit for the number of file descriptors that the user’s process may have open at one time.
Use -1 to set an unlimited size.
For example, to set the limit to 2000:
aix.user.attr.nofiles: 2000
This parameter corresponds to the aix.nofiles attribute in the /etc/security.limits file.
The default value is -1.
