[Serusers] memory configuration

Hello, I am having some problems configuring memory for SER.. Here is what I have in my test instance: Server: Linux x64 Real Memory: 4GB Database: MySQL/NDB SER Shared memory: 256M Children: 16 Subscribers: 40000 In test environment: Registrations per sec: 120 Call per second: 120 When the SER process was started last week, it had only 4000 subscribers provisioned. Then another 36000 subscribers were provisioned. The SER was running fine. But when I decided to bounce SER, it would not restart. It seems from the log file that SER ran out of memory trying to load the LOCATION database into memory upon startup, failing around row #3500. LOCATION table had in excess of 10000 records at that point. The related piece of the logfile is below.. I wonder whether it is a matter of configuration or is it a bug.. The system definitely seem to have enough memory to store those few tens of thousands of records.. Even at 1K each, it amounts to nothing.. Especially given that at runtime it handles that amount of location info easily.. It's only a startup that seems to be a problem. I tried to play with giving it more or less of shared memory.. It does not seem to be relevant.. For now I just have to clean up the LOCATION table each time before restarting SER. Obviously, it is not a nice workaround..
