JS Client app & busy Omnis server

Hi Thad,

Thank you for your reply.

I’m actually using the monitor window at that site to monitor the
connections (but running it in run time, so it is hard to trace what
actually is happening, I have also added a log when connecting to the
remote task and I see the log is added twice to the file)..
I don’t have a dev lic for a high number of users to run the same test in a
dev environment. I couldn’t reproduce the issue with a 5 users dev lic.

When the multiple connections issue occurs, the connection time and last
response time are exactly the same for the multiple connections.

As for the call to the form, I can only see one call to the form at a
time..But who knows what is going on when the server is busy and a new
request is sent to the server.
I hoped that there was a server.$state attribute that one could use to
handle cases when the remote task gets a request for a new connection and
the server is busy…

Thank you,
Mayada
