Hi Damien,
yes, you are right. Sorry, I didn't realize this. But I am not sure if 
locking tables is possible in this case. Because the next free alias is 
get directly from DB, but new alias is created by calling FIFO function 
of SER. It is SER responsibility to write the new alias to DB. However, 
this behavior is changed in new version of ser/serweb.

You may try to set:

modparam("usrloc", "db_mode", 1)

in your ser.cfg. Altought the tables still is not locked the probability 
  of generation two same aliases is much less.
