[Serusers] receive_msg: no mem for sip_msg

[g.billoudet at arwen-tech.fr]

Hi, thanks for help

I used serctl alias add 1234 sip:gwenael at arwen-tech.fr just after starting
ser :
- When I set modparam("usrloc", "db_mode", 0), ser works fine and I can
have phone calls but I can't use this alias of course...
- When I ser modparam("usrloc", "db_mode", 1), ser just doesn't work at all.

My aliases table is empty when I start ser. I am using ser 0.8.12.

  Gwen
