[sr-dev] acc to db has stopped working

[Juha Heinanen]

Found the reason why db acc had stopped working: I had removed
async_workers parameter.  Looks like acc module does not insert anything
if db_insert_mode=2 and there is no async workers.  From README, I get
the impression that it should be doing standard insert in that case:

  6.28. db_insert_mode (integer)

  If set to 2, async insert is used if the db driver module has support
  for it and if async_workers core parameter value is greater than 0. If
  not, then standard INSERT is used.
