    Smart Reporting Memory Leak Issue -

      Hi All,

       

      I am facing very frequent memory leak issues. I am attaching logs  in case anyone has faced it before.  I have already raised Initial JAVA heap size to 8GB so far  but it doesn't stop the issue occurrence , it just postpones it (e.g. the SR was going down in half day when JAVA heapsize was set to 2GB , now gradually i raised it to 4, 6 and 8GB , and every time the issue re occurrence  frequency is just reduced).  My environment is Linux with JAVA 8 .

       

      Behavior : 

       

      Once the issue occurs :

      -- We can not navigate to smart reporting via ARS Midtier and standard error page  is displayed .

      -- At the same time  smart reporting direct URL is accessible and i can login via siadmin user.

      --Scheduled reports either fail or blank attachments are sent to user with No data.

       

      The only solution is to kill tomcat service and restart Smart Reporting.

       

      Logs (Just Sample extract) :
