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

Fri Mar 2 12:42:04 CST 2007

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.
