Hi Isuru,
You have identified the root cause correctly.
All Gmail message reading operations use the same IMAPStore instance which
is created during the initial authentication with the connector. So, as u
said, due to the parallel invocation of "gmail.readMailMessage" operation,
the "[Gmail]/All Mail" folder in the IMAPStore will be opened and closed
in parallel runs.
To get rid of this, you can make the ESB iterator sequential, using;
sequential="true"
in your iterator configuration.
Thanks,
Sewwandi
