[SR-Users] Database errors with usrloc db_mode=1 and dmq_usrloc

[Daniel-Constantin Mierla]

Hello,

the error message:

Feb 21 00:11:25 csbc02 csbc[13916]: ERROR: <core> [db.c:481]:
db_use_table(): invalid parameter value

Is printed if the database table name is not given as parameter (eg,
null or empty). I pushed a patch to usrloc to print the table in the log
message, can you try with latest master (or patch from next commit) and
send again the log messages?

Cheers,
Daniel
