Hi OrientDB team,
We are using 1.7.8 community edition. I saw these message in my program.

WARNING: Caught I/O errors from Not connected (local socket=?), trying to
reconnect (error: java.io.IOException: Channel is closed)

WARNING: Connection re-acquired transparently after 14ms and 1 retries: no
errors will be thrown at application level
What doesn't this mean? Is it something I should worry about? It doesn't
seem to throw exceptions to my application. Is there a way I can catch this?
Sometimes I run into this error after the message above.
com.orientechnologies.orient.core.exception.OConcurrentModificationException:
Cannot UPDATE the record #23:63977 because the version is not the latest.
Probably you are updating an old record or it has been modified by another
user (db=v4 your=v3)

Error: Error occurred when loading file Hemostasis.SIF. Cannot UPDATE the
record #23:63977 because the version is not the latest. Probably you are
updating an old record or it has been modified by another user (db=v4
your=v3)
Is the first error the reason that caused the second error? My application
runs in a single thread using a single connection. I don't think there was
any other connection trying to modify that object.
Thanks,
Jing
