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

I see what your looking at. There is a problem on my side. We use sipp to emulate the endpoint phones for testing and someone hosed up the script part that builds Contact header. telno:IP is getting scrambled causing BYE to go to the ether......
 
Sorry to have bothered you........

The blacklist is happening because of a timeout. (From line 41 of the file you sent):

*snip*

*snip*

This request was sent before your logfile begins, but apparently some sort of timeout has occurred, causing the stack to blacklist.

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.

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.
