Description
I have been working on this project that I just added mDNS to. I use it to advertise the built-in web server, nothing more. After just a few minutes running, I get a ton of logging like this:
E (244434) mdns: Cannot allocate memory (line: 1767, free heap: 8337220 bytes)

Eventually I get a Core 1 panic'ed (corrupted stack) and the app restarts.
Sketch
// Advertise mDNS…
#if true
Serial.println("Advertising mDNS…");
if (!MDNS.begin("clock"))
{
Serial.println("mDNS init failed");
}
else
{
Serial.println("mDNS responder started");
MDNS.addService("http", "tcp", 80);
}

Other Steps to Reproduce
Note that I don't think this is actually out of memory, if the free heap number is to be believed. But I can't find the code actually generating the line in the source. I'm using ESP Arduino 3.2.0
