[Investigated] ioB2 errors on rescan

[ko0ky]

Over the past few hours my site keeps crashing although ioftpd.exe is still running as a process the sitebot croaks and drops offline and I am unable to connect to the site. Getting the following message in my systemerror.log. Also as reported before, on some COMPLETES i will get duplicate stats or duplicate completes for the same release. I dont know if this is related but on this particular crash (posted below) I did notice the duplication of the COMPLETE and STATS.
Thanks in advance for any help, or let me know how I can futher assist the stomping of this bug.
