Error description
A multi-threaded process of an authentication load module, such as pdosd, might hang due to a deadlock between two threads holding locks on mutex in security routines. Most of threads are blocked in global_lock_common, having stack similar to: _global_lock_common(??, ??, ??) at 0xd04f1620 _rec_mutex_lock(??) at 0xd012b084 _unload_secmethod(??) at 0xd01ed264 getuserattrs(??, ??, ??) at 0xd020a514 _getpwnam_shadow_r(??, ??, ??, ??, ??) at 0xd01ff080 _posix_getpwnam_shadow_r(??, ??, ??, ??, ??, ??) at 0xd01fc63c uid.getpwnam_r() at 0xd38e16fc
