I have a samba server that has been running for quite a while, without any problems. Last week, out of the blue, everybody lost connections. I restarted winbind and samba and all was well. It happened again, and again all it took was a restart. It happened over the weekend then again on Monday, when I noticed winbind was gone and just restarted that. When i happened again today I looked into why.
Winbind is dying with an internal error. Here's what it looks like in the messages file: Apr 2 11:25:50 <Server> winbindd[16996]: [2008/04/02 11:25:50, 0] lib/fault.c:fault_report(36) Apr 2 11:25:50 <Server> winbindd[16996]: =============================================================== Apr 2 11:25:50 <Server> winbindd[16996]: [2008/04/02 11:25:50, 0] lib/fault.c:fault_report(37) Apr 2 11:25:50 <Server> winbindd[16996]: INTERNAL ERROR: Signal 6 in pid 16996 (3.0.20b-2.1) Apr 2 11:25:50 <Server> winbindd[16996]: Please read the Trouble-Shooting section of the Samba3-HOWTO Apr 2 11:25:50 <Server> winbindd[16996]: [2008/04/02 11:25:50, 0] lib/fault.c:fault_report(39) Apr 2 11:25:50 <Server> winbindd[16996]: Apr 2 11:25:50 <Server> winbindd[16996]: From: http://www.samba.org/samba/docs/Samba3-HOWTO.pdf Apr 2 11:25:50 <Server> winbindd[16996]: [2008/04/02 11:25:50, 0] lib/fault.c:fault_report(40) Apr 2 11:25:50 <Server> winbindd[16996]: =============================================================== Apr 2 11:25:50 <Server> winbindd[16996]: [2008/04/02 11:25:50, 0] lib/util.c:smb_panic2(1570) Apr 2 11:25:50 <Server> winbindd[16996]: PANIC: internal error Apr 2 11:25:50 <Server> winbindd[16996]: [2008/04/02 11:25:50, 0] lib/util.c:smb_panic2(1578) Apr 2 11:25:50 <Server> winbindd[16996]: BACKTRACE: 30 stack frames: Apr 2 11:25:50 <Server> winbindd[16996]: #0 winbindd(smb_panic2+0x14f) [0x93e7cf] Apr 2 11:25:50 <Server> winbindd[16996]: #1 winbindd(smb_panic+0x27) [0x93e677] Apr 2 11:25:50 <Server> winbindd[16996]: #2 winbindd [0x928786] Apr 2 11:25:50 <Server> winbindd[16996]: #3 /lib/tls/libc.so.6 [0x1b60d8] Apr 2 11:25:50 <Server> winbindd[16996]: #4 /lib/tls/libc.so.6(abort+0x1d5) [0x1b7705] Apr 2 11:25:50 <Server> winbindd[16996]: #5 winbindd [0x96515b] Apr 2 11:25:50 <Server> winbindd[16996]: #6 winbindd [0x9653c9] Apr 2 11:25:50 <Server> winbindd[16996]: #7 winbindd(cli_krb5_get_ticket+0x230) [0x965850] Apr 2 11:25:50 <Server> winbindd[16996]: #8 winbindd(spnego_gen_negTokenTarg+0x53) [0x966553] Apr 2 11:25:50 <Server> winbindd[16996]: #9 winbindd [0xa0952a] Apr 2 11:25:50 <Server> winbindd[16996]: #10 winbindd [0xa0984e] Apr 2 11:25:50 <Server> winbindd[16996]: #11 winbindd(ads_sasl_bind+0x150) [0xa0a070] Apr 2 11:25:50 <Server> winbindd[16996]: #12 winbindd(ads_connect+0x1ba) [0xa02a3a] Apr 2 11:25:50 <Server> winbindd[16996]: #13 winbindd(ads_do_search_retry+0xf6) [0xa0fd96] Apr 2 11:25:50 <Server> winbindd[16996]: #14 winbindd(ads_search_retry+0x3f) [0xa1005f] Apr 2 11:25:50 <Server> winbindd[16996]: #15 winbindd [0x8e5e56] Apr 2 11:25:50 <Server> winbindd[16996]: #16 winbindd [0x8d6c2c] Apr 2 11:25:50 <Server> winbindd[16996]: #17 winbindd(winbindd_dual_userinfo+0x137) [0x8cb7b7] Apr 2 11:25:50 <Server> winbindd[16996]: #18 winbindd [0x8e949d] Apr 2 11:25:50 <Server> winbindd[16996]: #19 winbindd [0x8e98fe] Apr 2 11:25:50 <Server> winbindd[16996]: #20 winbindd [0x8e8fc0] Apr 2 11:25:50 <Server> winbindd[16996]: #21 winbindd(async_request+0x88) [0x8e8b98] Apr 2 11:25:50 <Server> winbindd[16996]: #22 winbindd(init_child_connection+0x179) [0x8d1789] Apr 2 11:25:50 <Server> winbindd[16996]: #23 winbindd(async_domain_request+0xb6) [0x8e90e6] Apr 2 11:25:50 <Server> winbindd[16996]: #24 winbindd [0x8d11db] Apr 2 11:25:50 <Server> winbindd[16996]: #25 winbindd(rescan_trusted_domains+0x48) [0x8d15f8] Apr 2 11:25:50 <Server> winbindd[16996]: #26 winbindd [0x8ca601] Apr 2 11:25:50 <Server> winbindd[16996]: #27 winbindd(main+0x505) [0x8cb0f5] Apr 2 11:25:50 <Server> winbindd[16996]: #28 /lib/tls/libc.so.6(__libc_start_main+0xda) [0x1a379a] Apr 2 11:25:50 <Server> winbindd[16996]: #29 winbindd [0x8c8f72] Apr 2 11:25:50 <Server> winbindd[16996]: Since this is a daily occurance, its rather annoying, for me and the users.
