When starthing Thunderbird you may see an error message that "Thunderbird is already running". But "already running" might not be a hang, so you should check taskgmgr Check taskmgr or ps to find 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.

# ldap address book - do you have an ldap directory address book defined?
# run netstat while Thunderbird is running - any thunderbird connections to ldap, imap mail server, or other protocols shown in for the netstat displaythunderbird process?
#* MS-Windows: open a dos command window (Start, Programs, Accessories, Command Prompt), then type '''netstat -abo > netstat.log''' and hit enter. then type '''more netstat.log''' to look for lines that show thunderbird.exe.

## list the netstat results in your problem report## If imap connections are shown in the netstat results above seen and if needed by the devoloper, get an [[MailNews:Logging|imap:5 log]] in a log file, which can be attached to a bug report# '''Steps to reproduce''' (STR) - Please determine 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 seealong 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.

# '''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. Anywhere you see "Firefox" in the instructions, please substitute "Thunderbird".
