Dear expert,
      I'm developing a frontend and I'm getting this kind of error at each event:

10:14:56.564 2018/05/04 [Sample Frontend,ERROR] [odb.c:5911:db_set_data1,ERROR]
online database full

If I run the mem command in odbedit I get the result at the end of this post.

Notice that I need to use an event size which is significantly larger than the
default one. I don't know if it is relevant for this error. I have in the ODB:

  /Experiment/MAX_EVENT_SIZE = 900000000

and in the frontend code:

  /* maximum event size produced by this frontend */
  INT max_event_size = 300000000;

  /* maximum event size for fragmented events (EQ_FRAGMENTED) */
  INT max_event_size_frag = 5 * 1024 * 1024;

  /* buffer size to hold events */
  INT event_buffer_size = 600000000;

Events seem to be properly stored in the output files, but I'm afraid I could
get some other problem.

Thank you for your help,
         Francesco
