Thanks so much - I see that in our queue and I'm following along now.
I note in the wp-toolkit daily log when it throws the error i get : /usr/local/cpanel/3rdparty/wp-toolkit/var/logs

resolved this issue - it was caused by a server reboot whilst backup tasks were in process - the processes never cleared out.
I went into sqlite sqlite3 /usr/local/cpanel/3rdparty/wp-toolkit/var/wp-toolkit.sqlite3
checked was in the right db .database then listed the tables .tables
once in there looked at the content of the tables SELECT * FROM LongTasks; and deleted the offending items DELETE FROM LongTasks;
Cleared the waiting tasks out from the various tables.
Just to add the server reboot was not done through the WHM panel - it was done through the host companies VPS control panel - as a hard reboot.
