New subject: [OpenSER-Users] Server crash when permanent User Location is present in DB ?!

16 Apr 2008

Hi

I've got a weird problem I do not manage to solve alone.

I'm using v1.3.0 with mysql.so and and usrloc.so, on redhat enterprise v4.

When there is a permanent user location in the database (added previously
with openserctl ul add), the server does not start:
- there is no log about any error,
- after starting the server, there is no running openser process

Is it a server bug or should I activate/configure something else ?

Below my signature is my configuration file.

Thanks in advance for your help
Pascal
