I think it is a binary/library compatibility issue.
Try starting lsws as the normal user specified during the installation, just run lsws/bin/lshttpd directly.

Also, you need to change a configuration file manully, lsws/admin/conf/admin_config.xml , search for some thing like <enableCoreDump>, set it to 1.

If it creates a core file under /tmp/lshttpd/, please send the core file to bug@litespeedtech.com.

I will take a look tomorrow. :-)
