Subject: Default write cache size for new equipments breaks compatibility with older equipments 
> > the main purpose of the event buffer write cache
> how to control the write cache size:

OP provided insufficient information to say what went wrong for them, but do try this:

1) in ODB, for all equipments, set write_cache_size to 0
2) in the frontend equipment table, set write_cache_size to 0

That is how it is done in the example frontend: examples/experiment/frontend.cxx

If this configuration still produces an error, we may have a bug somewhere, so please let us know how it shakes out.
