Need help to understand WinDbg Preview Analysis

[DV Telecom]

Hi,



Could you please help me to investigate the issue below?



When trying to sign out from Cisco Jabber application, click doesn't work or it takes time (kind of application freezing issue).



I took full dump on Jabber and use WinDbg Preview to analyse this problem.





Here is the output of my WinDbg Preview:
