I've created yesterday a local DNS on the hobbit server using bind that is working as slave for the Microsoft AD DNS so that I can use it without having the problem that a DNS/Network fault will not let hobbit resolve the name.
To test i used this command and it crash without "--no-ares" : bbtest-net --debug --report --ping --checkresponse --dnslog=/tmp/pippo --no-update
After I started to use this local DNS bbtest-net started to crash during the name resolution. Now it's working with --no-ares 007-07-26 20:48:07 Adding hostname 'ITROMEXV11VSSMTP1' to resolver queue 2007-07-26 20:48:07 Adding hostname 'ITROMMX10VSSMTP1' to resolver queue 2007-07-26 20:48:07 Processing 500 DNS lookups with ARES 2007-07-26 20:48:07 Got DNS result for host itromlx103 : 10.90.2.63 2007-07-26 20:48:07 DNS lookup failed for itrompx20 - status Domain name not found (4) 2007-07-26 20:48:37 DNS lookup failed for ent4001 - status Domain name not found (4) 2007-07-26 20:48:37 DNS lookup failed for kpitts - status Domain name not found (4) .... 2007-07-26 20:48:37 DNS lookup failed for sap2 - status Channel is being destroyed (16) 2007-07-26 20:48:37 DNS lookup failed for sun4e - status Channel is being destroyed (16) 2007-07-26 20:48:37 DNS lookup failed for itrompx01 - status Channel is being destroyed (16) 2007-07-26 20:48:37 DNS lookup failed for itromlx104 - status Channel is being destroyed (16) Aborted (core dumped)
