[SR-Users] When too many calls, calls does not complete, too much delay when placing calls

I had this problem on one (dual xeon) system. The cause was a very slow
disk system - it was SAS but the OS decided to use it as IDE - and the
killer was bandwidth logging by iptables.
Checking with wireshark it could sometimes take over a second for a
packet to get out of an interface.
When I changed the disk driver and turned off bandwidth logging all the
problems went away.
