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.

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. 

Also how much shared memory does SER allocate by default?  Would
increasing this number possibly help?

The server had been running for upwards of a month prior to this
problem.
