    Not able to load pages more than 3 times continuosly

    Sameer Darbha

      Hi

       

      JDeveloper 11.1.1.6, BPM/SOA 11.1.1.6, WLS 10.3.6, Database : MS SQL Server 2008 R2

       

      I am not very sure if it is related to BPM or ADF, but it looks more like an ADF error..

       

      We have a BPM process with some human tasks. The human tasks pages are ADF pages.

      The pages / user tasks are opened properly for a few times, but does not load after that, until we close all the browser windows.

       

      I am getting these errors intermittently whenever I try to open a human task page in the BPM Workspace.

      (Common observation is that for the first few times the pages open properly. After more than 3+ times of opening the same task repeatedly, I a getting these 2 errors).

       

      The page stops rendering after the last text '<div' tag.

       

      Following are the 2 exceptions we see in the logs of the server.

       

      We are using MS Sql Server 2008 R2 for database.

      I tried with both Type 4 XA and Non XA versions of the JDBC Connections, but still getting the same error messages.

       

      Can anyone please let us know if we might be missing anything.

       

      Thanks for any help.

      Sameer
