Interesting thing: I have 2 identical login01 and login02 machines (Rhel4, full updates). login01 is running old kernel (2.6.9-42.ELsmp), login02 is running the latest one (2.6.9-78.0.8.ELsmp). Both have autofs debug enabled and are running the latest autofs (autofs-4.1.3-234). Now: 1) login01: [EMAIL PROTECTED] ondrejv]# cat /var/log/debug.log* | grep "Dec 4 09:15:09" Dec 4 09:15:09 login01 automount[3939]: handle_packet: type = 0 Dec 4 09:15:09 login01 automount[3939]: handle_packet_missing: token 3533, name .raw_data Dec 4 09:15:09 login01 automount[3939]: attempting to mount entry /proj/.raw_data Dec 4 09:15:09 login01 automount[1649]: lookup(yp): looking up .raw_data Dec 4 09:15:09 login01 automount[3939]: mt->key set to .raw_data Dec 4 09:15:09 login01 kernel: automount[1649]: segfault at 0000000000000000 rip 0000002a95916be0 rsp 0000007fbfffd5c8 error 4 Dec 4 09:15:09 login01 automount[3939]: handle_child: got pid 1649, sig 1 (11), stat 0 Dec 4 09:15:09 login01 automount[3939]: sig_child: found pending iop pid 1649: signalled 1 (sig 11), exit status 0 Dec 4 09:15:09 login01 automount[3939]: send_fail: token=3533 Dec 4 09:15:09 login01 automount[3939]: handle_packet: type = 0 Dec 4 09:15:09 login01 automount[3939]: handle_packet_missing: token 3534, name .raw_data Dec 4 09:15:09 login01 automount[3939]: attempting to mount entry /proj/.raw_data Dec 4 09:15:09 login01 automount[1650]: lookup(yp): looking up .raw_data Dec 4 09:15:09 login01 automount[3939]: mt->key set to .raw_data Dec 4 09:15:09 login01 kernel: automount[1650]: segfault at 0000000000000000 rip 0000002a95916be0 rsp 0000007fbfffd5c8 error 4
Note that .raw_data map does not exist in the yp map so it should go into the negative cache - which happens correctly on login02: ov 28 23:27:43 login01 automount[4201]: attempting to mount entry /proj/.raw_data Nov 28 23:27:43 login01 automount[13394]: lookup(yp): looking up .raw_data Nov 28 23:27:43 login01 automount[4201]: mt->key set to .raw_data Nov 28 23:27:43 login01 automount[13394]: lookup(yp): key ".raw_data" not found in map.

Any explanation? Thanks, Ondrej _______________________________________________ autofs mailing list autofs@linux.kernel.org http://linux.kernel.org/mailman/listinfo/autofs
