[Samba] Samba AD/DC crashed again, third time in as many months
Hello to the samba users list again. I've got an emergency here, a Samba AD DC I've got deployed has crashed again, this is the third time since 12/17/2015 that this domain has failed completely. No power outages or unexpected shutdowns, samba simply fails to start, it appears my database is yet again corrupt: [2016/03/02 11:27:17.025235, 0] ../lib/ldb-samba/ldb_wrap.c:72(ldb_wrap_debug) ldb:

[Samba] Samba AD/DC crashed again, third time in as many months
I should mention that I have a backup generated using samba_backup script from 2/27/2016. I'm guessing I need to restore from this backup to recover. Please advise, these failures are killing me.

[Samba] Samba AD/DC crashed again, third time in as many months

Samba keeps failing like this almost every month.
