[Serusers] SER & SIPSAK: SER registration limitations

[Nils Ohlmeier]

Hi,

first of all: AFAIK the db_mode has almost no impact on the memory usage of 
SER.
To utilize more (shared) memory try the parameter -m for SER. That should 
allow you to register a lot more contacts.
The startup thing is another problem. There you are running out of private/pkg 
memory. This memory limit can only be increased during compile time.

Regards
  Nils
