Re: [Dev] Exception when Invoking GmailConnector ReadMailMessage Operation
Hi Sewwandi, Still if a client set sequent=false he might get the same error. Either the bug should be fixed or limitation should be documented. IMO it is better to fix it since it is a valid scenario for a client to set it false in case he expects parallel processing. Touched, not typed. Erroneous words are a feature, not a typo. ___ Dev mailing list Dev@wso2.org http://wso2.org/cgi-bin/mailman/listinfo/dev

According to the implementation
In GmailUtils inside readMails method, it fetches the AllMails folder
and open and close it for and every each message.Since it runs in a loop
there is a possibility to open the folder before close.Is this can be the
Issue or something else.

Re: [Dev] Exception when Invoking GmailConnector ReadMailMessage Operation
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.
