Thanks for letting us know that you have started to encounter this behavior again. I was able to reproduce this issue in your account a moment ago and have made our technical team aware that you have started to encounter errors of this nature once again.
Although we had previously done some work intended to minimize errors of this nature and things appear to have improved considerably since then, we will be making some additional changes during our maintenance period scheduled for this Thursday night which we hope will fully resolve the issue.
I was able to locate the support case you filed on this subject and will contact you again through that case as any additional information becomes available. We apologize for the continued difficulties.
