Re: [tor-relays] What does this message mean in my tor logs?

Hi all,

Iâm running a server with a couple of relays and was getting good overall performance (120+ Mbps) up until a couple days ago. For the last two days, the log for one of the two relays is showing thousands of the following message:

[notice] Resolved [scrubbed] which was already resolved ignoring

It seems that tor is getting duplicate DNS responses when it sends out a DNS query.
Are your resolvers configured correctly?

Have you configured a caching DNS resolver on your machine?
(This has been reported to increase throughput substantially.)

Prior to yesterday, I hadnât ever seen this message in my log (and the second relay on this same server/same IP is not showing any such messages). Since this started, my throughput has dropped from around 120Mbps to about 80Mbps. Looking around on the internet, I canât find anything about this message. My server is running tor 2.7.6 on Ubuntu.

A misconfigured DNS resolver is one of the common reasons Exit throughput drops.


Thanks for the fingerprint, Atlas confirms your relay is an Exit.
