Summary:                    [patch] Asterisk runs out of sockets
Description: 
The Parallels engineers have found a bug that takes down asterisk because
the server runs out of sockets, and also it degrades the performance
because over time it takes more and more time for the processor to find an
empty socket. The load on the processor grows over time,

I think it is perfect. It is 3 AM EST. There are about 50 open calls, 236
SIP Channels, but 873 file handles counted by lsof -i. I have proved it
this way. I changed the bindport in sip.conf and reloaded. There were no
calls coming in. I waited about 2 mins and all the sip channels
disappeared. It means that "sip show channels" showed nothing at all. So
Asterisk should be, theoretically, back to zero. But there were still 147
open file handles, but 100% of them were for the database connection. So
this patch does work. Please commit it.
