Re: InstantDB: Reconnection problem


Guy

If you're using InstantDB version 3.14 you should see a message to stdout
when you close the connection to tell you that the database is shutting
down, followed (quickly) by a message to say that the shutdown has
completed. If the message doesn't appear then there's probably another
database connection lying around.

I can't think of anything off the top of my head that would account for
this. In the idle period, do you see any database activity or memory usage?

Subject: InstantDB: Reconnection problem


>We are developping Web site using InstantDB and JRun/Apache (or Tomcat

>We connect to the InstantDB database (through a servlet), make some

>(but the servlet is running) and wait for a long period (4 or 5 hours),
>the problem doesn't seem to appear. If the time between two connections
