[asterisk-ss7] chan_ss7 - unstable link

[Low Yu Siang]

When I 'module unload chan_ss7', the memory allocated to asterisk immediately dropped to 0.4%. 

asterisk = 1.4.15 
zaptel   = 1.4.11
chan_ss7 = 1.0.10
uname -a = Linux scvideo 2.6.18-8.el5 #1 SMP Thu Mar 15 19:57:35 EDT 2007 i686 i686 i386 GNU/Linux
cat /etc/redhat-release = CentOS release 5 (Final)
