Here's the contents of the log file: [2006/07/22 23:13:40, 0] nsswitch/winbindd_dual.c:child_read_request(49) Got invalid request length: 0 [2006/07/22 23:18:23, 0] nsswitch/winbindd_dual.c:child_read_request(49) Got invalid request length: 0 [2006/07/22 23:30:08, 0] nsswitch/winbindd_dual.c:child_read_request(49) Got invalid request length: 0 [2006/07/22 23:47:14, 0] nsswitch/winbindd_dual.c:child_read_request(49) Got invalid request length: 0 [2006/07/22 23:53:35, 0] nsswitch/winbindd_dual.c:child_read_request(49) Got invalid request length: 0 [2006/07/24 23:17:29, 0] nsswitch/winbindd_dual.c:child_read_request(49) Got invalid request length: 0 It would appear that whatever the problem is, it's consistent.
