Yasser Zamani commented on WW-4310:
-----------------------------------
[~trananhtung30], OK, could you also reproduce the problem outside of your real
production environment? I reviewed Struts 2.3.16.3 and it prints the stack
trace only when devMode constant is true which is not recommended in production
environment. However, if you can not reproduce, we can again try a modified
version of Struts 2.3.16.3 temporally.

> 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.
