I'm not sure what those messages mean, but 6.5.x is VERY old.
Upgrading is worth it in so many ways, that even if it didn't fix this it
would be worth it. Most likely this will be fixed by upgrading, but it's
not likely you'll get a lot of help on troubleshooting a version that old.
Since the release 6.5.x, 7.0.x, 7.1.x, 7.2.x and now 7.3 have come out.
For one thing, 7.3 is literally about 100 times faster than 6.5.x, and
it's definitely more reliable and has a lot fewer bugs in it.
