I'm using FreeSWITCH (Build 13168M) and we're having intermittent multi-second delays on conference bridges with more than three participants (this is not a new issue - just bubbled to the top of the stack to address).

The server is running on Amazon's AWS c1.medium instance, CentOS 5.0 with Kernel 2.6.18 32-bit i386.

I recorded a conference which shows the problem nicely: http://cfowl.postinbox.com/c.wav

Callers are coming on via the internal sofia profile from various physical locations. I'm not sure how to proceed with debugging this issue - advice welcome.
