Hi everyone,
We are trying to use OrientDB with REST API and vert.x.
we have noticed that when we send many requests one after the other we are
receiving the following exeption:

after an investigation with a network sniffer we have noticed that orientDB
doesn't allow to reuse the same connection and it closes the connection at
the middle of the second request.
if we hold between the requests (about 100ms) it works fine since it
clothes the connection and the second request opens another one.
Is there any way for the orientDB to reuse the connection?
is there a better way to fire REST requests one after the other?
