Did you start Asterisk as user root, so it can use real-time priorities? The chan_ss7 architecture splits the work-load in two parts, only one of which has real-time requirements, and runs the critical part at a high real-time priority to make sure it gets sufficient CPU. However, Linux real-time priorities require root privileges. BTW, doing 60 calls within a single second, you might want to calculate whether you have sufficient bandwidth on your signalling link. But even so, it should not cause the MTP2 layer to drop. - Kristian.
