Re: [reSIProcate] DNS blacklist/whitelist problem on resip 1.1 RC1

Here's a bigger log snip. There really shouldn't be any DNS lookup for the offending IP Addr because I provide my proxy as an IP addr, not name.

Well, these logs give me no indication of why the stack is blacklisting that tuple. The only reasons this should happen is 
1) The remote endpoint sent a 503 with a Retry-After. 
2) The remote endpoint timed out. 
3) The transport to the remote endpoint failed.

Since you are using UDP, my guess is 2, but I need to see more logging to be sure.

Best regards,

I'm testing out resip 1.1 RC1 in a performance environment and I am seeing 503 errors being generated due to an IP blacklist. This seems to toggle an IP address (my one and only proxy) between whitelist and blacklist and vip. I don't profess to know what all these things are, but within about 1.5 seconds the below sequence happens.
 
Any ideas what's causing this?? I have more logs if you need.
