updraft plus database backup error

i was just trying to do a backup with updraft plus (free version). things do pretty well at first - even at the beginning of the database backup everything runs fine. but at a certain point the process stops with an error messages and resumes after a certain period ... but obviously runs into the same problem again. the log-file doesn't provide any valueable information to me - so i would highly appreciate help for that issue. see the relevant part of the log:
