      Description

      Hi Lukasz Lenart ,

      We are using struts-portlet framework in Websphere Portal server clustering ( 1 Deploy Manager and 4 Portal servers instances) in production.
      Currently there is one issue happen in one of 4 servers randomly. The exception is showing login form in set Property is null in one server, but at that time other 3 servers are working fine. This issue can happen in any one of 4 servers in our production environment. We have also raised few PMR to IBM team for this issue. But IBM said it is not caused by them. We need your help to check if any possible way to cause this issue in struts.

      If possible, pls share us your avaliable timing and contact, we would like to have a call with you and IBM support to identify root cause.

      ===IBM response=============
      When I refer the past PMR ( 18484,000,834) we shared on all the findings and waiting for your Application team feedback, as such I don't think any further action pending on IBM Support end. do check with Application team and can we ask Application team not using

      the code what Application team using is not an IBM API / service code "
      com.opensymphony.xwork2.util.logging.commons.CommonsLogger" , good to
      check with Application team to discuss with respective vender.

      The above error code from strut's application code, check with Application support and ask them to explore further.

      As I hope we all are in same page now, as PMR 20364,000,834 & PMR 18184,000,834 - findings Pointing same struts2 loging function, even application team explore why they enabled this log ? ,how this impacted the Application Interface page with user login error.
