This has been happening on many, but not all, of my http tests since 23:49:51 last night.

A couple of my xymonnet tests are reporting "DNS error".
There are no other details and the --no-ares xymonnet option didn't help.
Please help!

I have a similar situation for one particular system...in my case, it's likely an issue that the name I'm monitoring is actually a CNAME, and there are occasional timeouts when querying the server that's responsible for the domain where the CNAME record resides.
My guess is that you're experiencing timeouts with DNS queries. If the "error" states don't last longer than a single polling interval, that's your likely culprit.

I use "testip" on pretty much all my hosts, and have explicit tests for important DNS names. I don't think it's helpful for a service to be reported as unavailable, or not even tested, because a DNS lookup fails. (You can also run xymonnet with "--dns=ip" to get the same effect for network tests.)
However the "testip" and "--dns=ip" settings don't apply to web tests. Instead, you use a special syntax in hosts.cfg, for example:
10.1.2.3 # webserver1.example.com http://web1.example.com= 10.1.2.3/cgi-bin/testthis
