I applied a few patches by Azat Khuzhin to the Libevent 2.1 branch recently to resolve these; please check for his name in the commit logs to see them. Any interest in backporting these to 2.0?
from libevent.
His patch ( 14971a8 ) does seem related (and even addresses the issue), but as you can see from my code some nameservers were just installed. Maybe doesn't matter, but it seems like there is some way the nameservers are being removed. It's also worth noting that 5c710c0 solves the issue too.
I backported Azat Khuzhin's changeset to 2.0 here https://github.com/ghazel/Libevent/tree/20_evdns_resume_fix . Want a pull request?
from libevent.
A pull request would be great there, yes! Especially if the backport was at all nontrivial.
I think that the issue isn't that the nameservers are being removed, but that any requests inflight when clear_and_suspend wind up with NULL-valued nameservers.

Seems that patches are merged in https://github.com/nmathewson/Libevent/pull/79
Can this be closed?
