Hi Bruce,
indeed I have as working item a dynamic re-allocation for memory at
usrloc startup. This will be available soon and it will fix your problem
automatically.
regards,

You can increase the shm memory using -m parameter (see 'openser -h').
For the private memory you have to edit "config.h" and change the
value of:
#define PKG_MEM_POOL_SIZE 1024*1024
The recompile and reinstall.
The problem is that at start up, the user location records are first
loaded in private memory and then moved in shared memory, from where
will be used further. When you have large number of registered users,
then you have to increase the private memory as well. The issue will
be addressed in the near future.
Cheers,
Daniel

We are trying to scale to 50K users and beyond, but are running into
lots of issues with the SIP server. The biggest issue is the database
and database abstraction layer, which seems to want to allocate lots
of memory. This problem is exacerbated by the fact that memory is not
allocated dynamically, but from a fixed pool allocated at startup. In
particular, we fail at startup when reading in a location database
with only a few thousand entries. We also run into problems with the
shared memory segment since the default initial allocation is so
small. However, this is adjustable via a command-line parameter so
it's less of an issue.
Has anyone investigated communicating directly with the database and
getting rid of the in-memory representation? It seems like this is
the only way to scale to very large numbers of subscribers, and it
solves other problems as well.
We would be interested in contributing to this effort, but might need
some guidance.
Thanks for any input or suggestions.
