Thunderbird uses this file to track your downloaded POP3 messages:

	http://kb.mozillazine.org/Popstate.dat

There have been some bugs in the past that have left the popstate.dat file empty or corrupted.  A full disk lead to me hitting the problem.  You could search https://bugzilla.mozilla.org/ to see what bugs have been fixed and what ones are still open.  You may want to update Thunderbird to the latest release also.
