Hi rvkvino,

Once again the log does not show any particular problem.
Also, given that there is no evidence of the loop CONNECTING -> DISCONNECTED:WILL-RETRY in the server log, it is very likely that the create_session requests just can not reach the server.

Regards,
Giuseppe

I have discussed with ionic team via forum regarding this limited connection pool. They are saying we don't have any restriction on

connection. Still we are facing this issue. Is there anyother solution or idea is there?

Giuseppe Corti

Hi rvkvino,

This puzzled me a lot.
The attached client console snippet show the typical retry cycle that happens when the server is unreachable; ie. the server is down or the client network configurations do not allow to reach it.
But in your case, these conditions do not hold since the same client can connect successfully several time before starting to fail.

Unfortunately in the debug client logs provided previously in this thread not there is no precise evidence of the error case.
So we really need the logs, both client and server, whit an issue case clearly highlighted.

Alternatively, you could try to recover the previously explored solution, that try to use a single instance of LightstreamerClient for all the pages.

Regards,
Giuseppe

Hi everybody,

Is there anyother solution or idea is there? I have the same problem.
Thanks in advance.

Regards.

Giuseppe Corti

Hi gsantos,

Please, could you also share some more information on your case and the same log files (both server-side and client-side) requested previously in the discussion?
Crossing information from different cases will make it easier to discover the ionic problem that prevents sometimes Lightstreamer from opening connections.

Regards,
Giuseppe
