Are you sure that libasync_wmi_lib.so.0 is not a symlink form 
libasync_wmi_lib.so.0.0.1? libasync_wmi_lib.so.0 would be library 
reference, and libasync_wmi_lib.so.0.0.1 is actual library file with 
version number. New version would then have for example 
libasync_wmi_lib.so.0.0.2 and libasync_wmi_lib.so.0 symlink would be 
changed to point to that new file. That way you always know which 
version is in use but your apps are now confused.
