since we pass the IP addresses through a environment variable, the number of IP is limited by the size of the variable. currently is 4K.
If LSWS is reading configuration through Apache httpd.conf, it should be fine, just the web console cannot list all of them.
As a temp solution, we probably can build a version for you and incrase environment variable size limit from 4K to 8K. We may have to change the way that IP addresses being passed.
