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.

Friends,

We are testing our SER set up using SIPSAK.

Are there any limitations in terms of the number of registered subscribers that

can be kept by SER in memory or in database?

We tried with both db_mod 0 or 1. After some 40,000 registrations, SER starts

Giving "No memory left" messages and sometimes terminates as well. And with

db_mode=1, SER can not startup again, giving

We checked the machine and out of 2GBytes of memory only about 10Mbytes

Were used up.

Any ideas?
