I can confirm this behavior, forwards work ok until the limit is reached. Setup is a single DC with less that 6 machines joined to the domain and maybe another 6 machines pointing at this DNS.
Does anyone want the gdb info that was stated from a prior thread back in issue 10? interim fix: I just added ulimit -n 8192 to the start script and a cron to restart samba twice a day for now. samba version 4.1.0pre1-GIT-456f821 ------------- snippet from the log -------------- [2012/09/25 12:46:14, 0] ../source4/smbd/server.c:475(binary_smbd_main) samba: using 'standard' process model [2012/10/03 18:07:09, 0] ../source4/dsdb/dns/dns_update.c:294(dnsupdate_nameupdate_done) ../source4/dsdb/dns/dns_update.c:294: Failed DNS update - NT_STATUS_IO_TIMEOUT [2012/10/03 18:17:09, 0] ../source4/dsdb/dns/dns_update.c:294(dnsupdate_nameupdate_done) ../source4/dsdb/dns/dns_update.c:294: Failed DNS update - NT_STATUS_IO_TIMEOUT [2012/10/03 18:27:09, 0] ../source4/dsdb/dns/dns_update.c:294(dnsupdate_nameupdate_done) > > ---------- Forwarded message ---------- > From: [email protected] > To: [email protected] > Cc: > Date: Thu, 11 Oct 2012 07:52:57 -0400 (CDT) > Subject: Re: [Samba] Internal DNS stops forwarding > > > Hi Felix, > > > >> I think it is.
