If you close, shut down or exit Thunderbird (or Thunderbird stops on its own) and you see the Thunderbird '''process''' is still running in MS-Windows task manager | If you close, shut down or exit Thunderbird (or Thunderbird stops on its own) and you see the Thunderbird '''process''' is still running (in MS-Windows task manager aka taskmgr, or linux ps process status) then you have a shutdown hang. When starthing Thunderbird you may see an error message "Thunderbird is already running". Check taskmgr or ps to see whether thunderbird is there. If you don't see thunderbird listed then you do not have a hang. | ||
'''What to do:''' 1. Go through the full [[#Symptoms|symptoms]] list below. 2. If a [[#Reported Bugs|Reported Bug]] is an exact match then cc yourself on the bug, but please only comment if you have new data to add. 3. If no bugs match, then report a new one, and provide detailed symptom information. In summary, just commenting that you see a hang is not useful - please support your report with symptom data. | '''What to do:''' 1. Go through the full [[#Symptoms|symptoms]] list below. 2.

# '''Steps to reproduce''' (STR) - Determine a full list of steps which seem to cause the hang. This list is a sequence of actions (1. xxxx, 2. yyyy, 3. zzz, etc) you did just '''before''' you shut down. Plus the things you see along the way on the screen. You may need to experiment to find steps that are most reliable, and also eliminate steps which aren't needed to reproduce the problem. If you can't seem to find a reliable set of steps, don't let that stop you from checking the bug list below or filing a bug report with the information you have collected. | |||
# '''Obtain a hang stacktrace''' - Please get a stacktrace using Thunderbird symbol server using _'''hang'''_ instructions in the references below, then attach text file containing stacktrace to a bug report.
