Re: [reSIProcate] reSIProcate DNS SRV lookups very slow on VPN

Also, later on, REGISTER is denied with a 401, and a second REGISTER is sent with credentials. Between the first and second REGISTER, the same DNS

Why are there 8-9 seconds gaps between queries ? Has anyone seen this
problem before ?


Wow. I've seen slow DNS before, but typically it is due to my application not calling ::process() in a timely fashion in the stack. Are you running HEAD from SVN or something else? The general idea in reSIProcate is to always query the DNS, or use a cache. Later versions of reSIProcate from SVN include a local caching nameserver to assist with SRV server migration.

So, I guess you should:

        a) check that you are calling process sufficiently.
        b) let us know what reSIProcate codebase you are seeing this in.
