Well, it's definitely a bug with the latest versions. I upgraded the
original instance I had which was running fine under 2.040006 since March
of last year. This one also is exhibiting the same issues with jobs queued
since 5:30pm yesterday.
Error logs on that instance since last restart yesterday afternoon are:
