William Bardwell created TS-2358:
------------------------------------
Summary: DNS does not fail-over promptly for DNS server returning
SERVFAIL
Key: TS-2358
URL: https://issues.apache.org/jira/browse/TS-2358
Project: Traffic Server
Issue Type: Bug
Components: DNS
Reporter: William Bardwell
If I have 2 dns servers listed in my resolv.conf and the first one is returning
SERVFAIL for something that I try to lookup, ATS takes a long time to fail
over, and won't do it for the first request to look something up. Using normal
system commands (host, ping etc.) with the same resolv.conf work fine.
I tried various config values with out much improvement. I could make it fail
in 40sec instead of 60sec for the initial failure...
debug logs will be attached, doing one DNS and then waiting a while and doing
another. (Doing more before enough time has passed don't seem to help much.)
