Vertica 6.1.2 error_message table not in line with vertica.log

Hi, On Vertica 6.1.2 in the error_messages table I see a few of the following ERROR messages reported (I have truncated message): "A Mergeout operation is already in progress on projection..." The error code is: 67,264,837 But when I look in vertica.log for the corresponding error I do not see it in there? All the other entries in this table appear to match what is in the log file, would be helpful if anyone knows why this particular error does not. Thanks, Mark
