Well, seems to Symantec Endpoint Protection soft has some problems with AnyConnect or vice versa. When on machine (Windows XP SP2 in my case) is AnyConnect and SEP version 11.0.4014.26 or (latest) 11.0.4202.75 then when AnyConnect is connected smc.exe takes high CPU and working is almost impossible. Interesting that with SEP version 11.0.4000.2295 is ... seems to ... everything OK. SEP can connect with SEPM and other services seems to work also OK and machine is responding well in general. Any ideas? More thanks, Alar.
