There are two functions to do that, one check the last write access, the other the last write access if the run is running. The alarm condition looks like:

While the odbxx API has been successfully used since the last months, a potential
problem with large ODBs surfaced. If you have lots of data in the ODB and load it
into an object like

After some thought, I changed the API again and removed the flag in the constructor,
so the system now automatically choses the best algorithm depending if the client
is connected to a local or a remote API. So in all cases you use again the old syntax:

The problem lies in your function mhistory_init_one() in Mudas.js:1965. You can only call "new MhistoryGraph(e)" with an element "e" which is something

At the run start mlogger writes the ODB to the .mid file. This needs conversion (binary ODB -> XML ASCII) which can take time.
