Dear developers, Sorry for my disturbance again, but this time I got really no way to deal with such a problem during the last 3 days. When I enabled the isolate-worker, the log hinted "cannot load profile.xml". No matter how I configured the run-as-user and run-as-group (such as nobody:nogroup, root:root, ocserv:ocserv which I added additionally) and the profile.xml path, it still cannot work. However once I switched off isolate-worker option,it worked. Hence was there anything I missed? Or could you please give me a brief instruction kindly? Just let me know if you need more information. I run the ocserv-0.10.8 with gnutls-serv 3.3.15. Please! I was urged to push certain strategy and information to my Cisco clients (e.g. AutomaticCertSelection, ServerList and MobileHostEntryInfo etc..), while I got no idea what the risk would be if without isolate-worker. Thank you for your patience and looking forward to your reply. Regards, Yick
