[Serusers] Sometimes ser crash and how to support multi gateways

Hi all, I use RPM packet for redhat linux 7.3. My system is redhat linux 7.3. Kernel is 2.4.20-24.7. Now SER usually works fine but seldom it down about 1 time per week. I can't find why I down. How can I find it in a simple way. Now I use a gateway to connect to PSTN. When traffic is up, I need to add more gateway. Now I use forward function to transfer those calls to PSTN to gateway if it find the call is call to PSTN. If there are more than one gateway, How can I balance calls to those gateway.
