When working with the mobile application on my Samsung Galaxy and I try to edit anything in the application it logs me off of the Salesforce.com app. I then get an error message id #441160759-89581(1169423391). I have uninstalled the app and reloaded and continue to have the same issues. I've checked with my local IT department and they are unsure of the issue.
The error id is stack trace number (a.k.a a gack). Salesforce support can get access to the server to tell you what this means so it may be worth logging a support ticket for more information.
