indexing bug

I had this happen once before and just reindexed the whole thing and everything worked fine but now it has happened again so I am sending you the log files.  I'm not sure of all the events that led up to it but at some point the indexer started indexing after a download (just like before) but then at some point it stopped with no warning of an error.  Normally I would just assume the indexing was finished exept that whenever I do a search there is a yellow label informing me that my search results may not be complete until indexing is finished.  When I exit out of L4 and then reboot the computer then go back into L4 the indexer starts up for a few minutes and then just stops with no error messages- it just stops indexing- and I am still left with the yellow label in search.  When I just restart L4 without a reboot the indexer does not start at all.  The posts I have looked at have mentioned crashes but this is not quite the same as the indexer just silently exits as if it is finished but leaves me with that label in the search box.  Please advise.  I am assuming I will need to do another compete reindex tonight.
