I'm not sure which log you are referring to. The server itself has been rebooted by the customer to return functionality. I found the errors after the fact.
Look in the log for lines conatining: "qm_status" , "heap size=", "dumping all allocked. fragments:". They should appear before ser shutdown.
Nothing like that in the syslog or any other log that I can find. There are errors in the logs from SER right up to just prior to the reboot:

Is the local memory allocated per listening process (as reported by 'ps') or per child process (as configured in ser.cfg) or based on something else? Just trying to get a grasp on how much the change will effect the memory usage in my environment.
per listening process ( total no. of processes = child_no * no_of_listening_addresses + 3).
So, with a child_no of 4 and 1 IP listed for listening, I'm looking at 8 listening processes or ~8 Megs of local memory allocated to SER?
Also how much shared memory does SER allocate by default? Would increasing this number possibly help?
32 Mb. In this case it will not help since this is not shared mem. The shared mem. runs out (usually :-)) when ser is in statefull mode (tm is used for forwarding) and a lot of calls are handled almost simultaneously (within sip expire time limits). This also depends on the CPU power (if the machine can handle only 100 cps due to cpu limits you will never exceed the default 32 Mb). On a dual athlon 2000+ which can handle ~4900 cps, 256 Mb are enough (ser -m 256).
The system is a 1.1 Ghz Celeron with 128 Megs and SER's it's only function. So, if I'm following correctly, it might be a good idea to increase the share memory a bit, but the local memory would help more?
