Setting ithe max_map_count to reasonable value shoudl work for everything, e.g. 65536 should be large enough for the system and reasonable for the test as well. AFAIK the value we have on tumbleweed was adjusted just because of Steam and the rest of the system works fine with much smaller value. -- Cyril Hrubis chrubis@suse.cz -- Mailing list info: https://lists.linux.it/listinfo/ltp
