Description
I have a lot of connection to different servers and my app can work for about 5000 different connections to other servers, but after that got SIGABRT. It uses dns_base to make async dns requests with evhttp_connection_base_new(). Here is backtrace and warnings from app.
[warn] event_del: event has no event_base set.
[err] evdns.c:4253: Assertion req->type == DNS_IPv4_A || req->type == DNS_IPv6_AAAA failed in evdns_getaddrinfo_gotresolve
Program received signal SIGABRT, Aborted.
