Hello,

I've finally found the key to reproduce your issue.
The problem arises whenever you subscribe to a certain list of fields but the server publishes updates only for a limited number of such fields.
In your case (accordingly to your log) you subscribe to 24 fields, while the adapter publishes updates for only 6 fields.
This is obviously a bug of the flex client library.

We already have a fixed version of the library in our repositories.

So You've now two possibilities to solve your problem:
avoid the subscription of not-updated fields (if possible) OR write an email to support@lightstreamer.com asking for the fixed version.

Thanks for your patience,
Bye!
