Re: [lwip-users] help with mDNS sending a DNS_RRTYPE_SRV query

Hi

Antonio, didn't you already figure out a couple of mails back that the 
problem is that your stack is too small so you get a stack overflow in 
mdns_readname? The recursive function has a max depth check so you 
shouldn't be in an infinite recursive loop.
